Several existing models of two body abrasive wear have been surveyed and summarized and a new 3 D simulation model for prediction of wear rate of materials has been established by combining Monte Carlo method with numerical simulation approach. The abrasive wear parameters are determined with Monte Carlo method, the random surface of the abrasive particles is generated based on a so called “target hitting” method. The abraded surface is remembered by dissecting, which provides a new way to deal with the side ridge and the calculation of abrasive rate. The predicted wear rates of mild carbon steel based on the model agree well with the experimental ones. Therefore, the model is of advantage and validity in predicting the abrasive wear rates of materials.
