摘要
中低碳钢精密件采用37%或20%盐酸溶液酸洗后进行磷化实验。结果表明,精密件在37%的盐酸溶液中酸洗内径尺寸增加0.039～0.048μm/s,在20%的盐酸溶液中酸洗内径尺寸增加0.025～0.042μm/s;在37%的盐酸溶液中酸洗外径尺寸减小0.049～0.055μm/s,在20%的盐酸溶液中酸洗外径尺寸减小0.030～0.044μm/s。磷化后尺寸增加约为4～10μm,为精密件设计提供参考。
Machinery precision parts made of medium-carbon steel and low-carbon steel had been pickled by HCl with the concentration of 37% and 20%,and then phosphated. Experimental results showed that the inner circle diameter increased by 0. 039 ～ 0. 048 μm / s in 37% HCl pickling,and increased by0. 025 ～ 0. 042 μm / s in 20% HCl pickling. The outer circle diameter decreased by 0. 049 ～ 0. 055 μm / s in 37% HCl pickling,and increased by 0. 030 ～ 0. 044 μm / s in 20% HCl pickling. After phosphating the diameter increased by 4 ～ 10 μm.
