可用Bend test 或高温法测试， 具体方法如下(摘录)：
The test speciments shall be bent repeatedly through an angle of 180 degree on a diameter equal to the thickness of the specimen until fracture of the basis metal occurs. Following fracture of the basis metal, it shall not be possible to detach any areas of the coatings with a sharp instrument. When the plated articles are not readily adaptable to the bend test, adhesion may be determined on the plated article by cutting the plating from the basis metal at the interface in a continuous path, and examining at four diameters magnification to determine whether removal has been caused by the cutting away of an adherent plate or by the lifting of th nonadherent plate.
Alternate adhesion test.
The test specimens shall be baked at a temperature of 215+/-5 degree C for a period of 30 minutes, to determine adhesion of the plating. |
