摘　　要：从实验和理论两方面研究了化学镀Ni-P合金在无润滑磨损条件下的化学腐蚀磨损机理，探讨了化学镀Ni-P合金作为钻杆耐腐蚀磨损功能性镀层的可行性．结果表明：化学镀Ni-P合金在无润滑磨损条件下的磨损机理主要为剥层磨损，并伴随少量磨粒磨损．在无润滑磨损状态下，化学镀Ni－P合金不适合作为G105钢抵抗化学腐蚀磨损的功能性镀层．The chemical corrosive wear mechanism of electroless Ni-P coating under unlubricated wear was studied by test and theory and the possibility of as an anti-chemical corrosive wear coating on drill pipe was probed into. The results showed that electroless Ni-P coating appear mainly delaminate wear and lightiy abrasive wear under unlubricated wear. At the condition of unlubricated wear, it is not suited to eletroless Ni-P alloy as a protective coating on drill pipe.
