摘 要: 在自行研制的腐蚀磨损试验机上,研究了腐蚀学因素对化学镀Ni-P合金腐蚀磨损行为的影响。结果表明,当NaCl浓度为3. 5%时,化学镀Ni-P合金的腐蚀磨损速率、摩擦系数和腐蚀磨损协同作用率具有峰值特性。Nacl浓度升高将引起Ni-P合金的自腐蚀电位负移,温度升高将引起Ni-P合金的腐蚀磨损速率增大,协同作用率上升。化学镀Ni-P合金可以作为G105钢在NaCl溶液中抵抗腐蚀磨损的表面改性材料。

Abstract:The effect of corrosion factors on the corrosive wear behaviours of electroless Ni-P coating in NaCl solution was studied using a device made by authors. The results showed that electroless Ni-P coating had better of wear than G105 steel,and the main loss forms were the pure mechanical wear and the synergy between corrosion and wear.
