Abstract

It is known that alloying diamond-like coatings with transition 3D metals allows for significant modification of their structure and tribomechanical properties. The article compares Ti- and Cr-alloyed diamond-like coatings in real tribotests. The coatings were applied using the ion-plasma method using a BRV600 vacuum unit onto a 40KhN steel substrate by means of synchronized operation of an arc discharge and a pulsed laser. The mechanical characteristics of the samples were determined using the continuous indentation method on the NanoTest 600 measuring platform. It is noted that the mechanical characteristics of coatings depend significantly on the technological modes of coating application. Tribological tests were carried out using a ball-on-disk design, where a corundum ball served as the counterbody. Alloying diamond-like coatings with 3D transition metals has a significant effect on the tribological characteristics of the friction unit. All the examined samples had a low friction coefficient of 0.13–0.2, and the Cr-alloyed diamond-like coating demonstrated exceptionally high wear resistance.

Ti-和Cr-3D合金DLC涂层摩擦学特性的比较分析

众所周知，将类金刚石涂层与过渡3D金属合金化可以显著改变其结构和摩擦力学性能。本文通过实际摩擦试验对钛合金和铬合金类金刚石涂层进行了比较。利用BRV600真空装置，通过电弧放电和脉冲激光同步操作，采用离子等离子体法在40KhN钢基体上喷涂涂层。在NanoTest 600测量平台上采用连续压痕法测定试样的力学特性。值得注意的是，涂层的力学特性在很大程度上取决于涂层应用的工艺模式。摩擦学测试采用球盘设计，其中刚玉球作为counterbody。类金刚石涂层与三维过渡金属的合金化对摩擦单元的摩擦学特性有显著影响。所有检测样品的摩擦系数都很低，为0.13-0.2，并且cr合金类金刚石涂层具有非常高的耐磨性。
