Abstract
The composition and structure of heterophase coatings on VK8 (WC-8% Co) hard alloy cutting blades (inserts) were studied. The coatings were obtained by the methods of CVD of TiC with double magnetic-abrasive treatment and electric-spark alloying (ESA) with a TiCN-AlN-based composite as well as by combining these two methods. The wear resistance of WC-Co cutting blades with combination coatings was the best in tests on cutting the materials from SCh20 cast iron.
