Abstract
Abstract In this present review, wear are basic issues found in the piston. Thermal spray coatings are one of many techniques for adjustment of part's surface properties. The technology depends on the principle of melting and speeding of fine particles and their rapid solidification after effect on the substrate. Amongst all the techniques of thermal spray coatings, High-Velocity Oxy-Fuel and Plasma spray process is widely used in various applications. In this study, Al8Si20BN ceramic powder with explicit properties was selected, which was sprayed with high-speed oxygen fuels (HVOF) and plasma spray methods on aluminum alloys 2014. Both the coatings have same binder with equivalent rate. The coatings were characterizations were carried out with the help of Scanning Electron Microscope, X-ray Diffractometer, and Pin-on-disc wear testing machine. Its wear behavior was verified by the application of 5, 10, 15 and 20N loads of pins of the machine per disc, then the results of both methods were compared. According to the results, the models with HVOF coating are more durable than the models coated with plasma at different loads in a similar state.
