摘　　要：研究了化学复合镀Ni P Cf 工艺及碳纤维对镀速、镀层硬度和耐磨性的影响 ,探讨了碳纤维提高镀速、镀层硬度、耐磨性的机理。结果表明 :加入碳纤维 ,使Ni P合金镀速和镀层硬度显著提高 ;经 50 0℃时效处理后 ,耐磨性比普通Ni P镀层提高 5倍多。本工艺为 :2 0g/L硫酸镍 ,2 5g/L次亚磷酸钠 ,30g/L络合剂 ,1g/L加速剂 ,1mg/L稳定剂 ,微量表面活性剂 ,pH =4 .7,温度为 85±The effects of technological parameters and carbon fibre on the hardness and wear resistance of the deposit were investigated and discussed.The experimental results showed that the addition of carbon fibre could obviously increase the hardness.Afrer ageing at 500 ℃ the wear resistance of the Ni-P-C f coating could be 6 times as high as that Ni-P coating.
