热处理工艺对Ni-P-Cr_2O_3化学复合镀层组织与性能的影响

lnfluence of Heat Treatment on Microstructure and Properties of Ni-P-Cr_2O_3 Electroless Composite Plating

研究了热处理工艺对Ｎｉ－Ｐ－Ｃｒ２Ｏ３化学复合镀层组织与性能的影响。结果表明，复合镀层经４００℃×１ｈ处理后显微硬度最高。经６００℃×１ｈ处理具有较佳的耐磨性。经８００℃×１ｈ处理后仍具有较高的硬度和耐磨性。

The influence of heat treating process on the microstructure and properties of Ni-P-Cr_2O_3 electroless composite plating has been studied in this paper The results show that the composite plating can obtain the highest microhardness after heat treating at 400℃×1h and excellent wear resistance after heat treating at 600℃×1h.It retain high microhardness and wear resistance and corrosion resistance after heat treating at 800℃×1h
