【摘要】 本研究首先在镁合金表面上通过表面金属化工艺制备了一层均匀的金属膜,它可以使镁合金基体免于被化学镀液过度腐蚀,同时为化学镀提供了具有反应活性的表面,然后在其上进行化学镀镍。该工艺对环境无害,减少了化学镀过程对镁合金基体的损耗,提高了其加工精度,可延长化学镀液寿命,并简化了工艺过程。通过扫描电镜、电化学动电位极化测试,结果表明所得到的化学镀层性能良好,化学镀层耐蚀性有明显提高。更多还原

【Abstract】 In the present paper,a novel and simple pretreatment method for electroless plating on magnesium alloys has been described.A uniform metal film would generate on magnesium alloys by surface metallization,and it could protect magnesium alloys from excessive corrosion by bath,and electroless plating could process on it successfully.This process has no harm to environment and prolongs life time of bath.The Ni-P coating was studied through scanning electron microscopy(SEM) and electrochemical potentiodynamic polarization.Ni-P coating on nickel film exhibited good corrosion resistance properties in protecting magnesium alloy.更多还原
