摘要
本文用划痕法测定了Ni-P合金镀层的结合力;观察了划痕侧面镀层的失效形式;分析了三种评定结合力的参数。结果指出,临界载荷L_C、平均应力σ_A用于评定Ni-P镀层的结合力是有条件的,而B-W公式存在的问题更多。
The binding force of Ni-P plating is measured by scratch test in this paper. The modes of failure on side plating are observed, three parameters of assessing the binding force are analyzed. The results indicated that the critical load stress σ_A remain explanatory difficulties in assessment of binding force of Ni-P plating, and they have certain limitations. And the formula B-W hes much problems.
