Chemical Corrosive Wear Mechanism of Electroless Ni-P Coating
-
摘要: 從實驗和理論兩方面研究了化學鍍Ni-P合金在無潤滑磨損條件下的化學腐蝕磨損機理,探討了化學鍍Ni-P合金作為鉆桿耐腐蝕磨損功能性鍍層的可行性.結果表明:化學鍍Ni-P合金在無潤滑磨損條件下的磨損機理主要為剝層磨損,并伴隨少量磨粒磨損.在無潤滑磨損狀態下,化學鍍Ni-P合金不適合作為G105鋼抵抗化學腐蝕磨損的功能性鍍層.Abstract: 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.
