EFFECT OF PRETREATMENT ON CHARACTERISTIC AND CORROSION RESISTANCE OF ELECTROLESS Ni-Co-P DEPOSITS ON ALUMINIUM ALLOY
铝合金的前处理对其Ni-Co-P化学镀镀层沉积特性和耐腐蚀性能的影响

The effect of two pretreatment techniques namely double zincate-flashed Ni plating and pre-implantation on characteristis and performance of electroless Ni-Co-P coating on aluminum alloy were studied.The results showed that the morphology and corrosion resistance of electroless Ni-Co-P deposits were determined by pretreatment methods,and the composition of those was not influenced apparently.The corrosion resistance of electroless Ni-Co-P deposit with pretreatment of double zincate-flashed Ni plating was in...
