The high strength steel (100,000 psi minimum yield) piston rod has a ground, polished, and chrome plated surface.

高强度钢（100，000防扩散的最低收益率）活塞杆有一个理由，打磨，表面镀铬。

All these results show that severe plastic deformation occurred on the grinding surface, the strain strengthening is the basic reason for the increase of the yield strength in grinding affected layer.

这些结果说明，磨削表面发生了严重的塑性形变。冷作塑性形变强化是磨削影响层的屈服强度得以提高的根本原因。

Conclusions: Both etching of porcelain surface and use of silane yield higher bond strength, but the etching is the chief factor.

结论：使用酸蚀剂和硅烷偶联剂都能提高贴面烤瓷的粘接强度，但酸蚀剂起主要作用。
