本研究的目的是建立一个理论模型和相关的磨损模式图，以确定两体磨损（沟槽磨损）和三体磨损（滚动磨损）在微尺度磨粒磨损试验（也称为球孔磨损试验）中的主导地位。基于磨料颗粒穿透球和试样表面的连续介质力学模型，结合平衡的考虑，确定了两体和三体磨损过渡的临界条件。在不同的测试条件下，如磨料浓度和载荷，用不同的球和试样材料组合进行了微尺度磨损试验，并产生了一个磨损模式图，该图定义了磨料颗粒的运动规律。地图绘制在两个无量纲组之间作为垂直和水平轴：球和试样之间的硬度比，以及一个新引入的参数，表示接触的严重程度。在这项工作中产生的实验数据以及从以前的研究中获得的数据表明，该地图代表了微尺度磨损测试中的行为，适用于各种球和样品表面材料。(C) 2003 Elsevier Science B.V.版权所有
The objective of this study was to develop a theoretical model and associated wear-mode map to identify the regimes in which two-body abrasion (grooving abrasion) and three-body abrasion (rolling abrasion) dominate in the micro-scale abrasive wear test (also known as the ball-cratering abrasion test).The critical condition for the transition between two-body and three-body abrasion was determined from a continuum mechanics model for the penetration of the abrasive particles into the surfaces of the ball and the specimen, coupled with considerations of equilibrium.Micro-scale abrasion tests were performed with different combinations of ball and specimen materials, under different test conditions such as abrasive concentration and load, and a wear-mode map has been produced which defines the regimes of abrasive particle motion. The map is plotted between two dimensionless groups as vertical and horizontal axes: the hardness ratio between the ball and the specimen, and a newly introduced parameter which represents the severity of contact. Experimental data generated in this work and also taken from previous studies show that the map represents behaviour in the micro-scale abrasion test well, for a wide range of ball and specimen counterface materials.
