Abstract

In this paper, Cu/AlMgB₁₄ composites with by weight percent, 5, 10 and 20 % of the AlMgB₁₄ (referred to CA-5, CA-10 and CA-20) were fabricated by hot-press sintering method. The mechanical and dry-sliding tribological properties of the three composites were investigated. The results indicated that the densities of the Cu/AlMgB₁₄ composites were lower than copper, whereas the hardness higher. The friction and wear behaviors of the composites were strongly dependent on the AlMgB₁₄ content. The friction coefficient was in the range of 0.73-1.0 for CA-5, but it was always steady at about 0.2 for CA-10 and CA-20. Accordingly, the increase in the Al- MgB₁₄ concentration can improve the wear resistance of the composites.
