Sažetak
With daily growth of the world's industry scientists are faced with rapid and continues changes, visible on product's diversity, lifetime and high quality demands. As a material for cutting tools hardmetals (WC-Co) stand out as an optimal material comparing the price and tool lifetime. Coating technology is the main way to improve the cutting tools performance. The area of application for these types of coated materials is expanding with the development and application of ultra fine powder grain sizes, as well as the advancements in technology. One method of coating hardmetals is plasma assisted chemical vapour deposition (PACVD), rarely used for coating hardmetals with ultrafine grain size. In this paper the potential of using multilayer gradient PACVD coating on the ultrafine grained WC-Co hardmetal samples is explored. The samples were consoldated by two different powder metallurgy processes ; sinter-HIP and convetional liquid phase sintering in hydrogen atmosphere. Multilayer gradient coating system consists of TiN layer, gradient layer of TiN + TiCN and layer of TiCN. Coating thickness measurements and Rockwell adhesion tests were conducted.
