Abstract
The wear resistance of materials is a critical factor in prolonging the lifespan of equipment. This study aims to enhance the wear resistance and high-temperature solid lubrication properties of Ti3SiC2 by preparing Ti3SiC2/SiC composite ceramics with varying SiC content through powder metallurgy techniques. The research investigates the friction and wear behavior of these composites over a broad temperature range, focusing on the role of SiC in the frictional wear process. This analysis includes the establishment of dual variables-temperature and SiC content-as well as an examination of wear micromorphology, composition, and structure. The results indicate that the tribological properties of Ti3SiC2/SiC composite ceramics improve with increasing temperature and SiC content. The high wear resistance of these composites is attributed to the synergistic effects of oxidation, the formation of an oxide layer, and the mechanical properties of the matrix, rendering them suitable for superior solid lubrication applications.
期刊介绍:
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
