精细陶瓷（先进陶瓷、先进技术陶瓷）——评价陶瓷涂层附着力的洛氏压痕试验

[中文适用范围]： 本文件规定了一种通过使用洛氏金刚石压头压痕来定性评估厚度不超过 20 μm 的陶瓷涂层附着力的方法。压痕后形成的裂纹也可能表明粘结失效。压痕是用洛氏硬度计制成的。本文件中描述的方法也适用于评估金属涂层的附着力。该测试不适用于硬质基材上的弹性涂层。 [外文原描述]： This document specifies a method for the qualitative evaluation of the adhesion of ceramic coatings up to 20 μm thick by indentation with a Rockwell diamond indenter. The formation of cracks after indentation can also reveal cohesive failure. The indentations are made with a Rockwell hardness test instrument. The method described in this document can also be suitable for evaluating the adhesion of metallic coatings. The test is not suitable for elastic coatings on hard substrates.
