The main objective of this work is to model wear of a disc which was subjected to dry contact with a ball in unidirectional sliding. Tribological tests of sliding pairs were carried out using a tribological tester T-11 in a ball-on disc configuration. Stationary balls made of 100Cr6 steel with a hardness of 62 ± 2 HRC co-acted with rotating discs with 42CrMo4 steel with a hardness of 40 ± 2HRC. Discs were machined by lapping, grinding, milling, and vapour blasting. The values of the Sq parameter of disc surfaces were between 0.1 and 5.86 µm. Wear volumes of the discs were lower for bigger roughness heights. The simulation of disc wear was conducted on the basis of the repetitive contact between sliding surfaces. Strong correlation was achieved between the modeled and measured volumetric wear levels.

这项工作的主要目的是为圆盘的磨损建模，该圆盘在单向滑动中与球干接触。滑动对的摩擦学测试是使用摩擦测试仪T-11在球形圆盘上进行的。由硬度为62±2 HRC的100Cr6钢制成的固定球与硬度为40±2HRC的42CrMo4钢的转盘共同作用。通过研磨，研磨，铣削和蒸气喷砂对圆盘进行机械加工。圆盘表面的Sq参数值在0.1到5.86 µm之间。圆盘的磨损量较小，粗糙度较高。盘磨损的模拟是基于滑动表面之间的重复接触进行的。在建模的和测量的体积磨损水平之间实现了很强的相关性。
