【 摘 要 】

Corrosion of the components is a predominant factor which controls the life of metallic parts. Metals parts of various structures are often subjected to damage due to corrosion driven failures causing loss of functionality and dimensions. In order to reduce corrosion, there are two ways one is introducing new materials and the other is improving the existing materials by adding alloying materials or by surface coating techniques. Surface coatings are a feasible way to enhance the corrosion resistance of metallic materials, thus expanding the life span of the metal components. Aim of this paper is to draw comparison between various coating techniques and analyze which surface coating technique and coating materials improves the corrosion resistance of the materials. Further, in this review paper coat materials on the base material by mostly cold spray and plasma spray techniques. So, these two surface coating modification techniques are discussed in detail.
