标准摘要
[中文适用范围]: 本文件规定了一种基于压痕法测量热喷涂陶瓷涂层室温界面韧性的方法。 界面韧性是根据维氏硬度计引发的压痕角部裂纹的平均长度计算得出的,适用于单层或多层陶瓷涂层。 本文件中提出的测试程序旨在用于周围环境。 本文件推荐用于热喷涂陶瓷涂层,如热障涂层、耐磨涂层和电绝缘涂层。 [外文原描述]: ISO 20267:2017 specifies a method for measuring the interfacial toughness of thermal spray ceramic coatings at room temperature based on an indentation method. The interfacial toughness is calculated from the mean length of cracks emanating from the corners of the impression induced by a Vickers hardness tester, and it is intended for use with ceramic coatings with a single layer or multilayers. The test procedures proposed in this document are intended for use in an ambient environment. ISO 20267:2017 is recommended for thermal spray ceramic coatings such as thermal barrier coatings, wear resistant coatings and electrical insulating coatings.
