| Abstract |
In order to investigate the effect of the solid lubricants on the wear properties of tin-bronze alloys, Cu-l0wt%Sn tin bronze alloys containing WS₂ and MoS₂were produced by the powder metallurgical method and tested by a reciprocal type wear testing machine. The wear surfaces of the specimens and the counter steels were observed and analyzed by SEM, EDS, AES and XPS. Application of the solid lubricants in the alloy composites reduced the friction acting on the contact surface. Addition of WS₂ was effective to improve the wear resistance at the higher applied load since a uniform lubricating layer formed on the worn surface. MoS₂ in the samples was transformed to copper sulfides during the sintering process. This led to an increase in wear loss because the strength of the alloy matrix was lowered by the formation of copper sulfides. |
