Abstract

Seal wear caused by hard particles intruding into the seal surface is one of the main causes of seal failure. In this manuscript, the tribological properties of hydrogenated nitrile rubber (HNBR) in the intrusion of five different sizes of garnet particles into the friction pair were studied through the pin-disk rubbing pair. The experimental results show that the particles change the contact pattern of the friction pairs, thus changing the amount of rubber wear. Different forms of particle motion contribute differently to the friction coefficient, and the particle sliding on the rubber surface contributes the most. As the particle size decreases, the friction coefficient tends to increase and then decrease, which can be explained by energy dissipation theory.

粒度对氢化丁腈橡胶摩擦和磨损行为的影响

硬质颗粒侵入密封面造成的密封磨损是密封失效的主要原因之一。本手稿通过针盘摩擦副研究了氢化丁腈橡胶（HNBR）在五种不同大小的石榴石颗粒侵入摩擦副时的摩擦学特性。实验结果表明，颗粒改变了摩擦副的接触模式，从而改变了橡胶的磨损量。颗粒的不同运动形式对摩擦系数的影响不同，其中颗粒在橡胶表面滑动的影响最大。随着颗粒尺寸的减小，摩擦系数呈先增大后减小的趋势，这可以用能量耗散理论来解释。
