Abstract This paper presents results of both oxidation and tool wear tests concerning the couples consisting of Ni-and Ti-based alloys and TiAlN coating to determine its oxidation behaviour. Firstly, oxidation tests are performed in a special chamber at temperatures ranging from 700°C to 1000°C in air atmosphere. Secondly, the wear tests were carried out keeping the same temperature range. The surface morphologies, chemical elements and produced phases were analysed with SEM, EDS and XRD techniques. The results show that protective Al2O3 films are formed on the TiAlN coating surface. The prediction methodology for oxidation process and corresponding tool wear is proposed.

基于扩散偶和工具磨损试验识别 TiALN 涂层与耐热航空合金的氧化过程

摘要 本文介绍了由 Ni 基和 Ti 基合金和 TiAlN 涂层组成的对的氧化和工具磨损试验结果，以确定其氧化行为。首先，氧化测试在一个特殊的室中进行，温度范围为 700°C 至 1000°C，空气气氛中。其次，在保持相同温度范围的情况下进行磨损试验。用SEM、EDS和XRD技术分析了表面形貌、化学元素和产生的相。结果表明，在TiAlN涂层表面形成了Al2O3保护膜。提出了氧化过程和相应刀具磨损的预测方法。
