Özet

Surface engineering plays a great role in decreasing the cost of wear and corrosion losses in
industrial applications. Generally, engineering materials must have some specific
characteristics. These characteristics which are important in selecting material for specific
applications related with material structure and life-time. Generally it is difficult to find all
these features (mechanical and surface) 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. Today,
coatings are used in different fields of industry. Especially, in space industry components, gas
turbines, turbine rotor blades, ceramic coatings are widely used for improving the oxidation
and corrosion resistance and hardness, and for decreasing the wear. In this study, the corrosion
protective properties of PVD-TiN coatings were investigated and the relations between
corrosion protective properties and structural and wear properties were studied.
