Characterization of hydroxyapatiteynano-zirconia composite coatings deposited by high velocity oxy-fuel (HVOF) spray process
Hydroxyapatite (HA)ynano-zirconia composite coatings were successfully produced through high velocity oxy-fuel (HVOF) spraying of radio frequency (RF) plasma synthesized powders. Microstructure characterization and morphology analysis on the nano-structured coatings were conducted using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD), and d...
متن کاملApplication of High-Velocity Oxygen-Fuel (HVOF) Spraying to the Fabrication of Yb-Silicate Environmental Barrier Coatings
From the literature, it is known that due to their glass formation tendency, it is not possible to deposit fully-crystalline silicate coatings when the conventional atmospheric plasma spraying (APS) process is employed. In APS, rapid quenching of the sprayed material on the substrate facilitates the amorphous deposit formation, which shrinks when exposed to heat and forms pores and/or cracks. T...
متن کاملProduction of Ni65Cr15P16B4 Metallic Glass-Coated Bipolar Plate for Fuel Cell by High Velocity Oxy-Fuel (HVOF) Spray Coating Method
In this study, the newly designed bipolar plate for proton exchange membrane fuel cells (PEMFC) was produced by spray-coating the Ni65Cr15P16B4 metallic glassy alloy on Al plate. The Ni65Cr15P16B4 metallic glass was adopted as a coating material because of its excellent corrosion resistance and the high velocity oxy-fuel (HVOF) spray coating was used for the metallic glass deposition on the Al ...
متن کاملPossibilities of Utilization High Velocity Oxygen Fuel (hvof) Coatings in Conditions of Thermal Cyclic Loading
The item deals with the possibilities of utilization HVOF coatings in thermal cyclic loading conditions. There were evaluated three types of coatings based on WC-Co, WC-Co-Cr and Cr3C2-25NiCr. The quality of coatings was evaluated in terms of their adhesion as sprayed and also during the cyclic thermal loading, EDX analysis and evaluation of microhardness. Construction and structure of coatings...
متن کاملایجاد لایه سوپرآلیاژ بر روی فوم های نیکلی توسط عملیات پاشش گرمایی
Open pore metallic foams can be used for high temperature, high performance heat exchanger due to their high gas permeability and heat conductivity provided that skins properly attach to the foam’s struts on the surface. In the current study, a novel process was successfully developed to fill pores on the surface of the foam sheet in order to deposit skin on the foam specimens by thermal sprayi...
