【摘要】 计算并绘制了Ｎｉ－ Ｐ－ Ｈ２Ｏ系电位－ ｐＨ图，从热力学角度分析了电沉积Ｎｉ－ Ｍｏ－ Ｐ－ ＳｉＣ复合镀层的机理。结果表明，磷不能单独从水溶液中沉积出来，但它可以与镍以Ｎｉ３Ｐ的形式实现共沉积。更多还原

【Abstract】 The voltage-pH diagram of Ni-P-H 2O system in 298K standard condition was plotted by means of dependable thermodynamic data.The mechanism of electrodeposition Ni-Mo-P-SiC composite coating was analyzed with respect to thermodynamics.The results showed that phosphorus could not be co-deposited in solution.However,it could be co-deposited with nickel in type of Ni 3P.更多还原
