Abstract

Despite interest, no one to the best of our knowledge has compared the physical, mechanical, and tribological properties of nitride-based TiAlN and CrAlSiN coatings, nor diamond-like ion-plasma coatings (DLC). In order to identify the physical and mechanical properties, including the elastic modulus E and hardness H, we used nanoindentation methods, while experimental tribological testing of coatings was carried out on a TRB tribometer (Anton Paar TriTec SA). These tests revealed that during operation in the contact area of splined joints, a multilayer coating has better mechanical properties than a monolayer one under the testing conditions at specific loads comparable to operating loads. At the same time, a DLC coating features a much lower friction coefficient than do nitride systems. In addition, the paper presents the results of keeping friction units under observation by the acoustic emission (AE) method, which makes it possible to determine the running-in time for both coated and uncoated friction units.

改善重载摩擦系统的耐磨性及其监测技术

摘要

尽管有兴趣，但据我们所知，没有人能比较氮化物基TiAlN和CrAlSiN涂层，类金刚石离子等离子体涂层（DLC）的物理，机械和摩擦学性能。为了识别物理机械性能，包括弹性模量E和硬度H，我们使用了纳米压痕法，而涂层的摩擦学实验测试是在TRB摩擦计（Anton Paar TriTec SA）上进行的。这些测试表明，在花键接头的接触区域中操作期间，在与工作负载相当的特定负载下，多层膜在测试条件下具有比单层更好的机械性能。同时，DLC涂层的摩擦系数比氮化物系统低得多。此外，本文还介绍了通过声发射（AE）方法观察摩擦单元的结果，这使得可以确定有涂层和无涂层摩擦单元的磨合时间。
