在联合滚动和滑动的情况下，材料可能经历数百万次循环以及复杂的载荷和滑动条件，这可能会极大地影响其摩擦和磨损行为。结果表明，对于炭黑填充天然橡胶胶料与光滑氧化铝涂层圆盘的联合滚动滑动接触，牵引系数是滑移率的函数，与法向载荷有关，与滚动速度无关。结果表明，该材料副的磨损率与滑移率和轧制速度无关，但与滑动距离有关。结果表明，所有试验工况的磨损率大致相同(K ~ 1 × 10−4 mm~3·Nm−1)。球状试件的磨损形貌表明，这种磨损主要发生在接触区的左侧(内径)。版权所有©2015 John Wiley&Sons，Ltd.
Under combined rolling and sliding materials can experience millions of cycles as well as complex loading and slip conditions, which can dramatically affect their friction and wear behaviour. It was shown that for a carbon black‐filled natural rubber compound in combined rolling and sliding contact with a smooth alumina coated disk, the traction coefficient, as a function of slip percent, was dependent upon the normal load and independent of rolling velocity. The wear rate of this material pair was found to be independent of slip percentage as well as rolling velocity but dependent upon sliding distance. The wear rate was found to be approximately the same for all tested cases (K ~ 1 × 10−4 mm3·Nm−1). The worn profiles of the ball specimens showed that this wear occurred preferentially on the left side (inner radius) of the contacting area. Copyright © 2015 John Wiley & Sons, Ltd.
