The Influence of H, W, H/E, H-3/E-2, Structure and Chemical Composition on the Resistance of Ti-B-(N), Mo-B-(N), Cr-B-(N), and Zr-B-(N) Coatings to Cyclic Impact Loading

摘要

Coatings based on transition metal borides (Ti, Mo, Cr, Zr) were obtained by magnetron sputtering of ceramic targets in Ar and Ar-15% N-2 gaseous media. Resistance of coatings to cyclic impact loading against WC-6%Co ball was estimated at a load of 1 kN for 10(5) cycles using a CemeCon impact tester. The analysis of the relationship between the structure characteristics, chemical composition, mechanical and elastic-plastic properties, geometric parameters and the nature of the destruction of coatings is carried out.
