Abstract

In this study, WS2-dispersed Al composite material was fabricated by Compression Shearing Method at Room Temperature, using various WS2 content ratios. The mechanical and friction properties of the WS2-dispersed Al composites were measured. As a result, the density measurements showed that the compacted WS2-dispersed aluminum composite had a relative density of 95 to 99%. Tensile strength of WS2-dispersed Al has 200 MPa. The friction coefficient of Al/0.5vol.%WS2 was 0.14, a reduction of 83%, in comparison with the 1.0 friction coefficient of the pure Al matrix material. The addition of WS2 to the matrix systems used reduced the friction coefficient. Therefore, WS2-dispersed Al composite material is useful for maintenance-free material of slide member.
