喷射电沉积镍磷合金沉积速度试验研究

摘要

为了在亚磷酸盐体系中得到工艺稳定、光亮且沉积速度快的镍磷合金镀层,采用自行研制的喷射电沉积装置在45钢基体上进行了四因素五水平正交试验,优选出沉积速度最佳的工艺条件:电流密度300 A/dm2,镀液温度60℃,初始间隙1 mm,相对运动速度375mm/min.%A high speed jet-electrodepositing equipment was used to prepare Ni-P alloy. The influences of technology parameters on depositing rate of Ni-P alloy were studied. The results show that the best technology process is current density of 300 A/dm2, temperature of 60℃ , initial gap of 1 mm, speed of relative movement of 375 mm/min.
