标准摘要
[中文适用范围]: 本国际标准规定了热喷涂涂层在室温下的粘结强度分类方法,采用维氏硬度测试机进行。本国际标准对称为粘结指数的粘结强度进行分类,该粘结指数由最大无可见裂纹的压痕力得出,并适用于相对致密的金属涂层、陶瓷涂层和陶瓷金属复合涂层。本国际标准可用于每个涂层系统内的比较。不建议使用压痕法测试非常薄且多孔的涂层以及粘附强度小于内聚强度的涂层系统。建议将此测试方法应用于孔隙率小于约15%的涂层。 [外文原描述]: ISO 19207:2016 specifies the classification method of adhesive strength for thermal spray coatings at room temperature by using Vickers hardness testing machine. It classifies the adhesive strength, called adhesion index, evaluated from the maximum indentation force without visible cracking, and it is applicable for relative dense metal coatings, ceramic coatings and cermet coatings. It can be used within comparison within each coating system. The indentation method is not recommended for very thin and very porous coatings and also for the coating system with lower cohesion strength than adhesion strength. It is recommended that this test method can be applied for a coating of which porosity is less than approximately 15 %.
