本文通过实验证明,在常规工况条件下,金属干式滑动磨损中的主要机理是剥层磨损而非传统认为的粘着磨损.剥层磨损的程度可作为重磨损的特征.研究金属的耐磨性,应全面评价硬度指标的作用,并用断裂韧性KI(?)这一性能指标来确定硬度和韧性的最佳配合.
In this paper, experiments show that under normal working conditions, the main mechanism of dry sliding wear of metal is the peel wear instead of the traditional adhesive wear.The degree of peel wear can be used as the characteristics of heavy wear.Research on wear resistance of metal Sex, should fully evaluate the role of hardness indicators, and fracture toughness KI (?) This performance index to determine the best combination of hardness and toughness.
