摘 要: 在自行研制的腐蝕磨損試驗(yàn)機(jī)上，研究了腐蝕學(xué)因素對化學(xué)鍍Ni-P合金腐蝕磨損行為的影響。結(jié)果表明，當(dāng)NaCl濃度為3. 5%時(shí)，化學(xué)鍍Ni-P合金的腐蝕磨損速率、摩擦系數(shù)和腐蝕磨損協(xié)同作用率具有峰值特性。Nacl濃度升高將引起Ni-P合金的自腐蝕電位負(fù)移，溫度升高將引起Ni-P合金的腐蝕磨損速率增大，協(xié)同作用率上升。化學(xué)鍍Ni-P合金可以作為G105鋼在NaCl溶液中抵抗腐蝕磨損的表面改性材料。

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.
