Abstract
The need to reduce emissions has pushed the automotive industry toward the introduction of light-weight components, which has increased the interest in metal matrix composites (MMC) based on light alloys in applications where the strength-to-weight ratio, hardness and wear resistance are important. Age hardenable aluminum alloys reinforced with ceramic particles can meet these needs. This study analyses the influence of solution heat treatment and age hardening on the wear rate and friction coefficient of an Al-Cu-Mg-Sn alloy reinforced with TiB2 under sliding contact conditions against spheres of Si3N4 and AISI 52100 Steel. The experiments show that adhesion is the main wear mechanism, with abrasion as a significant secondary effect. The presence of TiB2 particles in combination with the ageing treatment contribute to the reduction of both friction coefficient and wear when compared with the same aluminum alloy without ceramic particles. The results are explained as a function of the hardness increase and the tribological compatibility between the alloy and contacting spheres. On a microstructural level, the severe plastic deformation associated to sliding wear is clearly observed. Dissolution of intermetallic particles is complete in the tribolayer and grain refinement is much stronger than what is observed in single-phase alloys.
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.
