Abstract

The wear-resistant coatings formed by the vacuum ion-plasma codeposition of titanium and carbon have been studied in this work. Single-layer and multilayer coatings with the systematically repeated [(Ti1 – xCx/a-C] pair are deposited onto P8M5 and 18KhN10T steel substrates. The highest erosion resistance is inherent in the multilayer [Ti0.2C0.8/a-C]40 coating with a layer thickness of 25 nm. The erosion wear rate of this coating is 1.6–1.8 times lower than the wear rate of the single-layer а-С and Ti0.2C0.8 coatings. The wear of [Ti0.2C0.8/a-C]40 occurs layer by layer without crumbling of individual square sections of the coating, thus increasing its service life. The interphase boundaries in the Ti0.2C0.8 composite layer, as well as the Ti1 ‒ xCx → а-С interface boundaries, serve as a barrier for the propagation of microcracks, decreasing the probability of macrocracking, which destroys the continuity of a coating.

摘要

在这项工作中,已经研究了由钛和碳的真空离子等离子共沉积形成的耐磨涂层。将具有系统重复的[(Ti 1 – x C x / aC)对的单层和多层涂层沉积到P8M5和18KhN10T钢基底上,多层[Ti 0.2 C 0.8 / aC] 40涂层固有的最高耐蚀性厚度为25 nm的涂层,其腐蚀磨损率比单层а-С和Ti 0.2 C 0.8涂层的磨损率低1.6-1.8倍[Ti 0.2 C 0.8 / aC ] 40涂层会逐层出现,而不会破坏涂层的各个方形部分,从而增加了使用寿命。Ti 0.2 C 0.8复合层中的相间边界以及Ti 1 ‒  x C x →а-С界面边界,充当了微裂纹扩展的障碍,降低了微裂纹的可能性,破坏了微裂纹的连续性。涂层。
