Abstract

Coatings based on transition metal borides (Ti, Mo, Cr, Zr) were obtained by magnetron sputtering of ceramic targets in Ar and Ar–15% N₂ gaseous media. Resistance of coatings to cyclic impact loading against WC–6%Co ball was estimated at a load of 1 kN for 10⁵ 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.

摘要

通过磁控溅射陶瓷靶材在Ar和Ar-15％N ₂气态介质中获得了基于过渡金属硼化物（Ti，Mo，Cr，Zr）的涂层。使用CemeCon冲击测试仪在1 kN的载荷下进行了10 ⁵个循环，评估了涂层对WC–6％Co球的循环冲击载荷的抵抗力。对结构特征，化学成分，力学和弹塑性特性，几何参数和涂层破坏性质之间的关系进行了分析。
