ISO 26423:2009规定了通过凹坑研磨法测定陶瓷涂层厚度的方法,该方法包括研磨球形空腔和随后对凹坑进行微观检查。
由于焊坑尺寸测量中引入的不确定性,该测试不适用于涂层和/或基底表面粗糙度超过涂层厚度20%的情况。
ISO 26423:2009 specifies a method for the determination of the thickness of ceramic coatings by a crater grinding method, which includes the grinding of a spherical cavity and subsequent microscopic examination of the crater.
Because of the uncertainty introduced into the measurement of crater dimensions, the test is not suitable for use where the surface roughness of the coating and/or substrate exceeds 20 % of the coating thickness.
