“HARDNESS AND WEAR ANALYSIS OF HIGH VELOCITY OXY FUEL SPRAY COATING ON AISI 1015 MILD STEEL SUBSTRATE” - A REVIEW

Mechanical Engineering

High velocity oxy fuel spray coating process is an effective surface engineering technique for its good thermal protectiveness, high hardness and wears resistance. The process covers a wide range of industrial applications including manufacturing, textile, and paper industries, and so on. To improve the micro hardness and wear resistance of mechanical components, high velocity oxy fuel coating has been applied to deposit of WC-17Co coating on low carbon AISI1015 substrate. The phase constituents and microstructure of the composite coating will investigate using optical microscope (metallurgical). Hardness at the coating cross section and wear rate measurement . Experimental data will be take according to orthogonal array to choose three process parameters and three levels. The experimental data will be optimizing by full factorial methodology, and give mathematical equation by regression analysis.
