摘　　要：研究了不同pH值条件下所得低温镀铁层的沉积速率、显微硬度和腐蚀速率等性能。结果表明:当pH值为1.0时,镀层获得最佳的综合性能;随着pH值的上升,显微硬度下降;pH值较高时,所得镀层的显微硬度、耐蚀性和结合强度都比较差,且沉积速率较慢。The deposition rate, microhardness and corrosion rate, etc. of low-temperature iron coating obtained at different pH values were studied. The results show that the best comprehensive performance can be achieved when pH = 1.0. The microhardness were reduced with the increasing of pH value, and deposition rate, microhardness, corrosion resisitance and bonding strength were worse at higher pH value.
