High velocity oxy-fuel spraying : theory, structure-property relationships and applications by V. V Sobolev( )

10 editions published in 2004 in English and held by 831 WorldCat member libraries worldwide

High Velocity Oxy-Fuel (HVOF) Spraying is widely used now for many industrial applications and is probably the best among the thermal spray techniques for some specific needs, e.g., for deposition of the cement coatings. Both industry and research laboratories have a need to improve their understanding of the HVOF spray processing in order to develop the optimum conditions and effective control of HVOF spraying which enables production of the quality coatings. Addressing this need is the main objective of this book

2 editions published between 1993 and 2019 in Spanish and held by 2 WorldCat member libraries worldwide

"Se han obtenido distintas aleaciones policristalinas de base cobre así como monocristalinas de ZuCnAlCo, las cuales han sido caracterizadas quimícamente, estructural y calorimétricamente. Se ha utilizado un nuevo método para conferir el efecto doble memoria de forma, el cual se basa en la estabilización de martensita inducida por tensión. A partir de las aleaciones fabricadas, se han estudiado las variables que afectan al proceso de educación: temperatura, tiempo de educación, deformación, efecto de tensionar en las diferentes fases, efecto de la estructura laminada inicial, concentración de defectos y la presencia de limites de grano, definiéndose en todos los casos el óptimo de los mismos que confiere el valor máximo del efecto doble memoria de forma.Se ha realizado ciclado manual, en ausencia de tensión externa, con el objetivo de evaluar el grado de EDMF adquirido por las distintas aleaciones en función de la variable estudiada en cada caso, determinándose la curvatura de la forma fria y de la forma caliente para los distintos ciclos realizados.Todas las muestras educadas han sido caracterizadas estructuralmente mediante las distintas tecnicas de microscopia SEM, TEM y alta resolución, lo que ha permitido postular un posible mecanismo de educación que tiene lugar al educar mediante martensita estabilizada.Las muestras utilizadas en el estudio del efecto del tiempo de educación sobre el grado de EDMF han sido caracterizadas calorimétricamente despues del proceso de educación, contrastándose los resultados de las temperaturas singulares de transformación antes y después de educar. Se ha estudiado el fenómeno de envejecimiento mediante microscopia y microdurezas y se ha evaluado la cinética del proceso."-- TDX
Titanium dioxide coatings obtained by thermal spray technologies and their functional application by Marc Gardon Ramos( Book )

2 editions published between 2013 and 2014 in English and held by 2 WorldCat member libraries worldwide

The main subject of this thesis is the fabrication of functional titanium dioxide coatings by means of Atmospheric Plasma Spray (APS) and Cold Gas Spray (CGS). Functional role may be understood as the capacity of TiO2 surfaces to respond in a determined way under certain conditions. Firstly, conventional coating processes, sensing mechanisms and overall efficiencies were deeply studied. As regards to experimental results, it was observed that H2 contained in the plasma mixture could reduce TiO2 towards non stoichiometric or stoichiometric compounds such as titanium sub-oxides (TiO2-x) or Magnéli Phases (TinO2n-1) respectively during the in-flight of the particles. Large accumulation of oxygen vacancies in the crystal lattice of rutile led to a donor level to the conduction band. Therefore, a corrosion-resistant ceramic material with a low electrical resistivity was obtained on ceramic tiles. This unexpected procedure led to deposit APS TiO2-x / TinO2n-1 coatings on stainless steel and apply them in electrochemical bi-polar batteries. Then, from the created feedback thin stainless steel and aluminium films, carbon-polymer composites or nickel foams as common standard electrode materials were selected and coated. Produce the active layer of a metal oxide gas sensor using APS fed by TiO2 was still a target to be accomplished. With the aim of offering more innovation to conventional metal oxide sensors, it was determined to build-up the sensing layer on a thin polymeric flexible substrate. It was possible to reach certain spraying conditions that avoided thermal degradation of the polymer. Furthermore, heterogeneous disposition of the coating, where some areas were coated and certain spots uncoated provided electric contact between the electrodes and structure that eased elastic deformation of the film. Satisfactory performances were obtained testing the response of the device in front of a target gas and radiation. Thenceforth, transition to thermally less-aggressive technologies was carried out. It was decided to focus the efforts on CGS, which does not require melting the material for being deposited. Subsequently, nanostructured anatase was used as feedstock in order to achieve photocatalytic layers with large specific surfaces for applying them in the degradation of different contaminants. It was used a powder able to create chemical bonds with the substrate and among the particles at the impact. Unfortunately, feeding system was repeatedly clogged because of the high agglomerating capacity of the powder. Blends were prepared with copper and microstructured TiO2 that flowed appropriately so as to avoid the obstruction of the pipelines. First, Cu/nano-TiO2 coatings were deposited using spraying conditions that favoured the deposition of nanostructured anatase at the top surface, which assured the development of the photocatalytic process. Samples successfully degraded toluene in gaseous phase. On the other hand, micro-TiO2/nano-TiO2 blend was not suitably deposited onto steel. Ceramic particles may not deform plastically. Thus, chemical bonds with the substrate and among particles had to be boosted for building-up the coatings. Substrate surface based on APS TiO2-x with controlled roughness provided composition, hardness and required geometry for adhering nano-TiO2 particles. In this way, CGS nano-TiO2 coatings were tested for degrading phenol and formic acid in liquid phase. The obtained results equalized or even improved the performance of sol-gel coatings. Metallic Ti coatings were previously deposited onto the polymer by CGS for afterwards spraying nano-TiO2, following the know-how gained in CGS nano-TiO2 photocatalysts. Again, lower layer acted as a bond coat between the original substrate and nanostructured anatase. Osteblast cultures were tested on PEEK, CGS Ti on PEEK and CGS nano-TiO2 deposited on CGS Ti layer. Higher cell adhesion, proliferation and differentiation were obtained as long as CGS coatings were applied, which leads to an improved bioactivity of polymeric implants
Microstructural characterization and mechanical properties of 9%Ni steel welds by submerged arc welding process using nickel-base alloys by Pablo Ozaeta Laverde( )

2 editions published between 2017 and 2018 in English and held by 2 WorldCat member libraries worldwide

Natural Gas with more than 80% methane has a liquefaction temperature around -165 ° C. Temperature at which the gas reduces its volume by a factor of 600/1. This operating temperature makes the use of ferritic materials unfeasible because they have a brittle fracture mode below a critical temperature, called transition temperature. For the construction of large containers, the most commonly used material is Steel A-553-T1 which has a nominal content of 9% nickel and whose crystalline structure is formed by a martensite matrix with some austenite reacted. This microstructure is achieved through double heat treatment; Tempering and tempering. To weld this steel, for this application, it is not possible to use materials of 9% Ni feed, in view of the impossibility of performing the necessary thermal treatments to achieve homogeneity of properties. On the other hand, the austenitic welding consumables present a ductile behavior with a high energy absorbed even to -196ºC and within these NiCrMo family nickel base alloys have a high mechanical strength, and a coefficient of thermal expansion close to the steel 9% Ni. Within this family of nickel base alloys, the Hastalloy C-276 alloy has been used, which increases its mechanical strength by solid solution, the main alloys being chromium and molybdenum both about 15% and with 2.5% of Tungsten and 5% iron. Although this is an alloy that is essentially single-phase Gamma, the last liquid is usually transformed into carbides or TCP phases as the pass Mu and P. These three phases have a very close composition so that their identification through the EDX is not possible . Currently, most of the tanks being built have a storage capacity between 150,000 and 200,000, so the sheet thickness of 1 was ferrule between 27 to 50mm, implying that the welds are multi-pass, Requiring between 16 and 30 passes to fill the joints of this first ferrule. Normally the vertical joints are welded with manual or semi-automatic processes while the horizontal joints are welded with automatic submerged arc process. According to the atmospheric tank design standards for cryogenic storage, the thickness of the sheets is determined by the Maximum Admissible Efforts that are calculated from the mechanical strength of the weakest structural element, the base metal or the weld joint. In the case of welding, the mechanical strength of the weld is determined from the cylindrical specimen tensile test obtained from the deposited metal, from the homologation coupon of the welding process. During the homologation of the manual or semi-automatic procedures, the results obtained in the tests of longitudinal and transverse traction are equivalent. In the case of automatic welding In addition to the low values obtained from the cylindrical tensions of the weld metal of the horizontal joints with respect to the transverse tensions, it is very often observed that an important difference in the resistance presented by the different tensile tests of the same welded specimen , These differences being much greater than the observed difference between two experimental conditions. Prior to this experimental work, 6 other tests and a few procedural approvals were carried out, in which sheets of 12, 21, 26.5 and 27 mm of thickness were used, with 2.4 mm and 1.6 mm threads always of the classification AWS A5.14 ER-NiCrMo-4, corresponding to the Hastalloy C-276 alloy, with different fluxes, stiffening levels, cylindrical probe diameter etc. This PhD work was carried out on the seventh test carried out in the summer of 2008 at Lincoln Electric Cleveland, where 4 fluxes, 2 wire diameters, alternating and continuous current and two voltage levels were tested, with an experimental design 23 with each flux. As all DOE tests were performed, 8 specimens were welded per flux, and a total of 32 specimens were welded. The purpose of this test was to select the best flux wire pair, and determine the optimum parameters to maximize the mechanical strength of the weld metal. The base material used in this experiment were A553 T1 steel sheets, with 9% Ni and annealed and tempered with a thickness of 21mm. The joint design of these specimens is asymmetrical and unbalanced "X" with a 1mm bead and a 2mm spacing. Following the actual joint design of the production plates. In order to prevent the melting bath from being picked up, a flux backing was placed. The tests performed on each specimen were as follows: Cylindrical traction welding metal: 4 per test pieces Charpy V Notch at -196 ° C Macro General Chemical Analysis, performed on the side faces of the macros. Chemical analysis on tensile specimens. Microhardness tests Vickers and Knoob. The wire-flux pair selected in these tests has been used for the welding of eight tanks: three in Spain: two in Gijón 2011-2013 and one in Bilbao 2014-2015; A tank in Chile, 2011-2013 and four other tanks in China, 2011-2013. With this pair, good results have been obtained in the approvals of welding procedures of these projects, both in the transversal tensions and in the cylindrical tensions, fulfilling the requisites of resistance necessary in each project. During the production, a welding metal with very few inclusions of slag has been deposited, presenting good degreasing and degassing. The objective of this research is to determine the factors that produce the variability of results in the tensile tests, correlating the structural and micro structural factors with the mechanical properties of the deposited metal, in order to maximize its mechanical resistance. -- TDX
