Abstract The influence of different axial loads on the tribological properties of Hydrogenated Nitrile Rubber (HNBR) under oil-based mud containing hard particles is studied through experimental and theoretical approaches. Friction and wear tests were performed by using pin-on-disc friction pairs. The findings indicate that the tribological properties of HNBR vary with axial load and wear time. The total friction coefficient can be divided into an adhesion term, a hysteresis term and an abrasive term through the analysis of tribological mechanism. The hysteresis term is due to micro-strain on the HNBR surface and overall deformation of the HNBR specimen. The variation of tribological properties can be well explained through the above theory and the hysteresis term is the main influence factor.

不同轴向载荷下氢化丁腈橡胶与硬质颗粒的摩擦学性能

摘要 通过实验和理论方法研究了不同轴向载荷对含硬颗粒油基泥浆中氢化丁腈橡胶(HNBR)摩擦学性能的影响。摩擦和磨损测试是通过使用销-盘摩擦副进行的。研究结果表明,HNBR 的摩擦学特性随轴向载荷和磨损时间而变化。通过摩擦学机理分析,总摩擦系数可分为粘附项、滞后项和磨蚀项。滞后项是由于 HNBR 表面上的微应变和 HNBR 试样的整体变形造成的。摩擦学性能的变化可以通过上述理论得到很好的解释,滞后项是主要的影响因素。
