Method & Evidence

AimTo investigate the influence of graphite and glassy carbon particles on the microstructure and tribological properties of copper-based composite materials intended for slide bearings.

MethodExperimental comparative study

ProcedureCopper-tin alloy composites were produced using both powder metallurgy and stir casting methods. Lubricating phase particles (graphite and glassy carbon) were introduced into the molten alloy with mechanical stirring, and titanium was added to improve wettability. The microstructure and tribological properties (friction coefficient and wear) of the resulting composites were then analyzed using microscopy and a high-temperature tribometer.

ContextMaterials science, specifically the development of composite materials for tribological applications (e.g., slide bearings).
