超级13Cr油管在P110套管中往复磨损实验研究

采用曲柄结构往复式磨损试验机对超级13Cr钢进行磨损实验,研究不同的接触力以及不同的摩擦频率对超级13Cr钢磨损性能的影响。实验结果表明,失重量及磨损效率都随着摩擦副的接触力的增大而增大,失重量及磨损效率也都随着摩擦频率的增大而增大。而摩擦系数随着接触力和摩擦频率的改变变化不大。采用SEM观察并分析磨损表面形貌,探讨磨损机理。表明超级13Cr油管与P110套管之间的磨损机理以黏着磨损为主,表面形貌为片状剥落和犁沟共存。

Study of Reciprocating Wear properties between Super 13Cr Tubing and P110 Casing

The wear experiments were conducted on super 13Cr steel by using crank structure of reciprocating wear testing machine. The effect of normal pressure and frequency on wear properties of super 13Cr steel were investigated. Experimental results show that the efficiency of both weight loss and wear efficiency increase with the normal pressure increasing, and also increase with frequency increasing. However, the coefficient of friction changed little with the changing of normal pressure and friction frequency. The surface morphologies of the wear were observed and analyzed by using SEM, and the wearing mechanism was discussed. It is show that wear mechanism of reciprocating wear of super 13Cr tubing-P110 casing is mainly adhesive wear. It has a surface morphology of flaking accompany with plough-grinding.
