摘要
在电连接器接触件表面镀层中,镍一般作为铜基底和表面金之间的过渡层,起到改善耐磨性和阻止金铜相互扩散的作用。基于正交实验法,使用直流磁控溅射技术,在铍铜插针基底表面制备镍过渡层,并测试镍镀层的厚度分布情况、表面粗糙度以及热震结合强度。通过极差分析法研究正交工艺因素对镍镀层厚度、粗糙度特性的影响,最后对测试结果进行综合分析,得到实验条件下镀镍的最佳工艺参数。
In the surface coating of electrical connector contact,nickel is generally used as the transition layer between copper substrate and surface gold to improve wear resistance and prevent the mutual diffusion of gold and copper.Based on the orthogonal experimental method and DC magnetron sputtering technology,the nickel transition layer was prepared on the base surface of beryllium copper contact pin,and the thickness distribution,surface roughness and thermal shock bonding strength of nickel coating were tested.The influence of orthogonal process factors on the thickness and roughness characteristics of nickel coating was studied by range analysis.Finally,the best nickel plating process under the experimental conditions was obtained through the comprehensive analysis of the test results.
