Comparative wear characteristics of tin and tic coated and uncoated tool steel

Wear characteristics of TiN and TiC coatings deposited by magnetron sputtering on D2 and D3 tool steels in contact dry sliding conditions have been investigated and compared to the uncoated. The thin films (∼4 μm) were characterised in their adhesion, hardness and chemically analysed. The results showed that TiC coated samples demonstrate greater wear resistance, with TiC D2 steel showed the best wear resistance. It was found that the substrate materials have an influence on the hardness and wear resistance of the system.
