STRENGTH PROPERTIES INVESTIGATION OF COMPOSITE COATINGS WITH QUASI-CRYSTALS OBTAINED THROUGH METHODS OF GAS DYNAMIC SPUTTERING

The work purpose is to investigate strength properties of composite coatings with quasi-crystals obtained through the method of gas dynamic sputtering. The object of development: quasi-crystals based on titanium carbonitride clad with nickel. In the course of the work there is offered a method for investigations of coating strength based on a pin and adhesive method with composites based on titanium carbonitride. The novelty of this investigation consists in obtaining new materials and investigations of their physical-mechanical properties. Composite coating on the basis of titanium carbonitride has shown high separation properties. The destruction took place in an intermediate layer between VN20 and KNTP35. During 10 mm bending there is a fine even mesh. At the impact load made there were not observed chips and separations that allow using coating data in heavy-loaded parts.
