Multilayered and multicomponent coatings are synthesized by a method of vacuum-arc sedimentation of metals and their nitrides on the basis of Тi, Zr, Cr, Mo. It is established, that erosion rate of coatings under cavitation decreases with increase in microhardness (Hμ) from 20 up to 32GPa and with growth up to 45 GPa - increases. It is established almost linear dependence of parameter a =Нm3 ⁄ Е*2 from microhardness of coatings
Многослойные, многокомпонентные покрытия синтезированы методом вакуумно-дугового осаждения металлов и их нитридов на основе Тi, Zr, Cr, Mo. Установлено, что скорость эрозии покрытий при действии кавитации уменьшается с увеличением микротвердости (Hμ) от 20 до 32 ГПа, а с ростом до 45 ГПа – увеличивается. Установлена квазилинейная зависимость параметра a=Нm3⁄Е*2 от микротвердости покрытий
