Any mechanical component stationary or in relative motion is exposed to severe surface phenomena like corrosion, wear, abrasion etc. To address these issues various surface treatment processes are in industrial practice. In recent times, coatings techniques have been identified as cost effective alternative to other surface modification techniques. Thermal spray technique proves to be the prominent method to among a large variety of processes available. HVOF method owing to its capability to provide wear and corrosion resistant coatings with characteristics like high hardness, adhesion, density (porosity <1%) is widely accepted across industries. Process parameters seems to have significant influence on coating properties like porosity level, oxide content, micro hardness and tribological performance of coating. This paper intends to investigate the effect of above mentioned process deposition parameters on physical, mechanical, wear, erosion and corrosion properties of coating.
