摘要

Composite materials are widely used in various industries to resist wear of machinery, equipment and facilities. The high wear resistance of composite materials benefits from a combination of hard reinforcing phase and ductile/tough matrix, which may effectively resist wear under various wear conditions. However, the performance of a composite could vary significantly in different wear situations, and the material may not be fully used with its maximum resistance to wear. For instance, a composite may possess extremely high resistance to sliding wear but perform less impressively when subject to impact wear. Wear is a complicated surface damage process, affected by many factors, such as microstructure, mechanical properties of the target material, and the wear condition. Microstructure may play a predominant role in resisting wear. However, the effect of microstructure on wear is difficult to investigate experimentally due to possible synergism between the microstructure and other factors. (Abstract shortened by UMI.)
