标准范围

ISO 26443:2008规定了一种通过使用罗克韦尔金刚石压头进行压痕，定性评估厚度达20μm的陶瓷涂层附着力的方法。压痕后裂纹的形成也可能揭示内聚破坏。压痕是用洛氏硬度测试仪制作的。所述方法也适用于评估金属涂层的附着力。该试验不适用于硬质基材上的弹性涂层。

ISO 26443:2008 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 may also reveal cohesive failure. The indentations are made with a Rockwell hardness test instrument.The method described may also be suitable for evaluating the adhesion of metallic coatings.The test is not suitable for elastic coatings on hard substrates.
