Thermal spray coating process is a surface modification technique in which a coating material like cermet’s, metallic, ceramic and some other materials in form powder are feed into a torch or a gun, the powder inserted into torch will be melted by high temperature developed by torch. Coating thickness can achieve by applying multiple layer of melted coated material. This paper aims at the study of mechanical characterisation of thermal spray single layer and multi-layer coatings. Coatings on SS 316L is followed by the wear test .It has been found that the wear rate of base metal i.e. SS 316L is more than single layer and multilayer coatings of Ni-30Cr powder (. The multilayers have shown the maximum resistance to the wear rate.
