对于新涂层的开发和摩擦学评估来说，使用通用和可靠的硬质薄层评估技术是必要的。为了快速评价硬质涂层的磨损性能，我们提出了一种新型的微浆液-射流冲蚀试验，即固体颗粒冲击冲蚀试验。我们正在使用一种新型的MSE测试仪(罐式测试仪)，它可以获得单位质量腐蚀的磨损量，在本测试中，腐蚀是平均尺寸为1.2微米的氧化铝颗粒。此外，通过评价TiN在高速钢表面的耐磨性，对MSE试验机进行了验证。新的MSE测试产生高度重复性的结果，并且对涂层的质量非常敏感。版权所有©2009 John Wiley&Sons，Ltd.
Versatile and reliable techniques for evaluation of hard thin coatings are necessary for the development and tribological assessment of new coatings. We have proposed a new type of micro slurry‐jet erosion (MSE) test, i.e. a solid particle impact erosion test for swift evaluation of wear properties of hard thin coatings. We are using a new type of MSE test apparatus (pot type tester) that makes it possible to obtain the wear loss per unit mass of erodent, which in this test was alumina particles with an average size of 1.2 µm. Its performance was evaluated by using a Si wafer plate under various test condition. In addition, the MSE tester was demonstrated by evaluating the wear resistance of TiN on high‐speed steel substrate. The new MSE test generates highly reproducible results and is very sensitive to the quality of the coatings. Copyright © 2009 John Wiley & Sons, Ltd.
