Surface treatment is a new improved treatment procedure which espouses the mitigation of root cause of failures and improves the internal properties of case-hardened alloy steel. Coating is one of the Surface treatment processes applied on the case hardened alloy steel by which a sign of tremendous improvement is shown in wear resistance. This is due to increase in hardness by coating fine particles of oxides of ceramics (OC) and tungsten carbide (WC) on the surface of alloy steel. The coating makes the surface of alloy steel completely devoid of retain austenite formation which is usually formed in other conventional heat treatment processes. An analysis has been made on the surface treated alloy steel which is coated with diverse blends of fine particles of OC and WC. The investigation of coating consists of numerous metallurgical processes to identify the coating powder specification, coating process, coating characteristics, micro-structure and wear resistance property for the surface treated alloy steel. The exploration reveals the best alternative among the coating blends of fine particles which are taken for analysis on base alloy steel.
