摘要
采用化学镀镍方法，在20Mn钢齿轮轮的表面上沉积0．013～0.018mm厚的Ni-P合金镀层，再经300℃恒温热处理2h，使镀层转变为晶体结构，其表面洛氏硬度（HR）大于62，达到进口同类产品的技术指标．
By adopting electroless nickel plating, a coat of nickel phosphorus alloy 0. 03-0. 018 in thicknessis deposited on the surface of 20 manganese steel gear shaft. After heat treating at constant temperature of300℃ for 2 hours, the coat changes into crystal structure. It has a surface Rockwell hardness larger than62, which approaches the technical indices of imported similar products.
