Abstract：As evaluation index of wear resistance, five index parameters which affect in three-dimensional surface-characterization parameters have been analyzed from the aspect of microcosmic geometrical characteristic.Base on the theory of grey relation method, an analysis model for the evaluation index of parts-surface wear resistance is developed. According to the quantitative analysis of the influence of the five different three-dimensional surface-characterization and parameters on the wear resistance, the internal correlation of the three-dimensional characterization parameters and the wear resistance are concluded, and the effects of the weight of the three-dimensional surface-characterization and parameters are calculated on the wear resistance, and the main sensitive parameters affecting the abrasion resistance are concluded. The conclusion provides a theoretical foundation for building a three-dimensional surface-characterization-parameters system.
