请教。关于金属镀层！

</script>请问各位大侠：
检查镀层与基体的附着强度一般用什么方法？
哪些试验室有这些检测项目？
请不齿下教
谢谢hua_tan (2006-4-20 15:05:34)很简单呀.用介刀将镀层切为60个左右的1mmX1mm的小方格,然后用3M胶纸812,粘看是否脱落.yykdmagnet (2006-4-21 08:23:33)楼上的划格法是一个检测方法，另外还有专用的拉拔附着力试验仪，另外跌落试验也是一个检验方式，主要看客户的要求了lwxe (2006-4-21 09:15:00)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 inte**ce 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.jackmayor (2006-4-21 09:41:29)QUOTE:

高温测试倒是可以试一下，
再有请问一下跌落试验怎么做啊？
谢谢

唉，我这才刚考完试就冲到天涯来想放松一下的，谁知道又看到了另一份更难的卷子，哎，这啥时候才能学到头啊。

好，很好，非常好！
