摘要
应用电化学方法研究了酸度、添加剂硝酸钠对A3钢常温磷化的影响 .结果表明 ,在磷化液中加入适量的硝酸钠能明显优化常温磷化的动力学行为 .
The influences of pH value and the concentration of NaNO 3 on the phosphatizing performance for A3 steel were studied by electrochemical methods.It has been observed that the pH value is an important factor in phosphatizing process.However,the suitable concentration of NaNO 3 could improve the kinetic process during phosphatizing.Finally,a three step mechanism for phosphatizing at ambient temperatures was proposed.
