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

4 editions published in 2004 in English and held by 822 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
KCl-Induced High-Temperature Corrosion Behavior of HVAF-Sprayed Ni-Based Coatings in Ambient Air by Reza Jafari( )

2 editions published between 2017 and 2018 in English and held by 3 WorldCat member libraries worldwide

KCl-induced high temperature corrosion behavior of four HVAF-sprayed Ni-based coatings (Ni21Cr, Ni5Al, Ni21Cr7Al1Y, and Ni21Cr9Mo) under KCl deposit has been investigated in ambient air at 600°C up to 168h. The coatings were deposited onto 16Mo3 steel - a widely used boiler tube material.Uncoated substrate, 304L and Sanicro25 were used as reference materials in the test environment.SEM/EDS and XRD techniques were utilized to characterize the as-sprayed and exposed samples.The results showed that the small addition of KCl significantly accelerated degradation to the coatings. All coatings provided better corrosion resistance compared to the reference materials. The alumina-forming Ni5Al coating under KCl deposit was capable of forming a more protective oxide scale compared to the chromia-forming coatings as penetration of Cl through diffusion paths was hindered. Both active corrosion and chromate formation mechanisms were found to be responsible for Page 1 of 23ASM the corrosion damages. The corrosion resistance of the coatings based on the microstructure analysis and kinetics had the following ranking (from the best to worst): Ni5Al >Ni21Cr> Ni21Cr7Al1Y>Ni21Cr9Mo

Analyse de possibilités de formation de dépôts de biomatériaux par la projection plasma de solution. by Rolando Candidato( )

1 edition published in 2017 in French and held by 1 WorldCat member library worldwide

Hydroxyapatite (HA) is widely used as coating material for hip implant due to its exceptional bioactivity. It is also flexible and can accommodate ions into its structure. Zinc (Zn) is a good dopant ion as it stimulates bone formation and exhibits useful antibacterial characteristics which can help fight surgical infections. HA-coated hip implants are conventionally prepared by powder plasma spraying process. An emerging process called solution precursor plasma spraying (SPPS) is an interesting one as it allows for the deposition of coatings having nanometric/ submicrometric features. This research work presents about the fabrication of HA and Zn doped HA coatings by SPPS. The influence of starting solution precursors and operational spray process parameters to the microstructural characteristics of HA is discussed. The coating build-up mechanisms of the obtained coatings using different sets of precursors are presented. Moreover, different models are used to describe the mechanical properties of the SPPS HA coatings and are correlated to their microstructures. Mechanism of Zn doping to HA by SPPS and its role for inhibiting HA formationare demonstrated. Finally, the in-vitro behaviour under simulated body fluid (SBF) is presented. Bone-like apatite layer on HA coating"s surface is formed but the experiment validated the inhibiting effect of Zn to apatite formation
