Improvement of corrosion resistance by vacuum arc evaporation PVD thin film TiN coating
Journal Title: Carbon - Science and Technology - Year 2015, Vol 7, Issue 4
Abstract
Generally, engineering materials must have some specific characteristics and those characteristics which are important in selecting material for specific applications related with material structure and life-time. It is difficult to find all these features especially mechanical and surface properties in a single material. So the solution is found by increasing the strength of bulk material, and increasing wear and corrosion resistance of the surface. Therefore, engineering materials are selected from cheaper materials providing needed structural features, and the other surface characteristics are provided from coatings. Friction and wear of the sliding components in an automobile cause an increase in both fuel consumption and emission. Many engine components involved with sliding contact are all susceptible to scuffing failure at some points during their operating period. Therefore, it is important to evaluate the effects of various surface coatings on the tribological characteristics of the automobile parts. In this study, the corrosion protective properties of Vacuum Arc Evaporation PVD coatings were investigated and the relation between corrosion protective properties was investigated.
