Lubricated sliding wear behaviour of aluminium alloy composites [PDF]

, 2005
Interest in aluminium alloy (Al-alloy) composites as wear resistant materials continues to grow. However, the use of the popular Al-alloy-SiC composite can be limited by the abrasive nature of the SiC, leading to increased counterface wear rates.
