摘　　要：研究了不同化学镀工艺对高锰钢镀层组织和性能的影响。得出化学镀Ni-P的最佳参数为:NiSO_(4)·6H_(2)O质量浓度30 g/L;NaH_(2)PO_(2)·H_(2)O质量浓度35 g/L;pH值4.7。非晶态Ni-P镀层致密,厚度约25μm。镀层硬度由330 HV提高到600 HV以上,磨损体积减少。镀层的腐蚀电流密度从基体的8.51 mA/cm^(2)降低到1.82 mA/cm^(2)。镀层明显提高了高锰钢基体的表面硬度、耐磨性能和耐腐蚀性能。To study influence of different chemical plating processes on microstructure and properties of high manganese steel coating.The optimal parameters for electroless Ni-P plating are:NiSO_(4)·6H_(2)O mass concentration 30 g/L,NaH_(2)PO_(2)·H_(2)O mass concentration 35 g/L,pH value 4.7,Amorphous Ni-P coating is dense and has thickness of approximately 25μm.Coating hardness has been increased from 330 HV to 600 HV,resulting in decrease in wear volume,Corrosion current density of coating decreased from 8.51 mA/cm^(2) to 1.82 mA/cm^(2).Coating significantly improves surface hardness,wear resistance,and corrosion resistance of high manganese steel substrate.
