Wear Behavior of Graphite-Dispersed Al-Sn-Si Alloys


Article Preview

The stirring technique was used to produce Al-6mass%Sn-3mass%Si-1mass%Cu alloy with 5~8wt% graphite additions. The friction coefficient and wear loss of the graphite-dispersed Al-Sn-Si alloys were measured against commercial stainless steel (SUS304) in the boundary lubrication. Although the graphite particles added up to 8mass% do not improved the friction coefficient of as-cast alloys at the lower applied load, an applied load for the Al-Sn-Si alloy with 5~8wt% of graphite additions reaches 0.60MPa,whereas that for the non-added base alloy is only 0.45MPa.
