    銅基納米復(fù)合減磨涂料在P110S套管上的應(yīng)用研究

    Application Study of Nano Copper-based Composite Antifriction Coating for P110S Casing

    • 摘要: 采用HT-100型球盤式摩擦磨損試驗機，檢測銅基納米復(fù)合減磨涂料在P110S套管上的摩擦性能；將該涂料涂覆于P110S套管磷化接箍表面，并進行全尺寸上卸扣試驗。試驗結(jié)果表明：銅基納米復(fù)合減磨涂料可在P110S套管表面形成有效保護磷化層，并極大地降低試樣表面的摩擦因數(shù)；復(fù)合納米抗螺紋黏結(jié)涂層可有效防止螺紋表面發(fā)生黏結(jié)，抗螺紋黏結(jié)性能好；與接箍鍍銅相比，銅基納米復(fù)合減磨涂層具有良好的附著力，強度高、導(dǎo)熱性好、操作方便、成本低、實用價值良好。

       

      Abstract: The antifriction performance of the nano copper-based composite antifriction coating as applied on the P110S casing is tested with the HT-100 ball disc friction-wear testing machine.After being applied on the surface of the phosphorized coupling of the P110S casing, the coating is tested with the full-dimension screw-up and screw-off processes.The test result shows that the said coating produces an effective protective phosphorized layer upon the said casing, and remarkably reduces the friction factor of the specimen surface.The nano composite coating also has fine anti-galling performance.Compared with the coupling surface copperization process, the nano copper-based coating process has such advantages as excellent adhesion, high strength, good thermal conductivity, easy operation, high cost effectiveness and high-application value.
