摘　　要：为研究点火电阻NiCr功能层与Ni耐焊层的结合力对其耐焊性的影响,从NiCr箔的表面特殊优化处理以及电镀两方面进行工艺优化。结果表明:电镀前用点火电阻专用处理液水浴40℃处理(30±5)s,并且冲击镀镍时在滚筒增加PP珠,可明显改善点火电阻的NiCr层与Ni层的结合力,耐焊接热试验后点火电阻的阻值变化量从0.2Ω降低到0.05Ω以内。To improve the welding property of ignition resistance,and study the effects of binding force between NiCr alloy foil and Ni layer on welding property,the processing was optimized on specialization surface treatment of NiCr foil and electroplating.The results show that the binding force between NiCr alloy foil and Ni layer was improved obviously,and resistance changed from 0.2Ω down to less than 0.05Ω after welding heat test,with special liquid 40℃ water bath treatment for 30s before plating,and adding PPball in the roller during shock nickel plating.
