Summary

Carbide-metal composites, such as Cr3C2-Cu, Cr3C2-bronze and TiC-Cu, were prepared by infiltrating liquid metal into carbide skeletons with open micro-porosity at high temperatures. X-ray diffraction and scanning electron microscopy equipped with energy dispersive spectrometry were used to characterize these materials. The resulting microstructures consisted of two interpenetrating three-dimensional skeletons. There is no sign of porosity at the interface indicating good wetting between the metal and ceramic. The combination of a ceramic and a metal in the composites resulted in unique combinations of mechanical and electrical properties. Abrasion and friction tests showed that the composite materials had better abrasion resistance than that of ceramics such as Al2O3 and SiC as well as lower friction coefficients than that of SiC. Tests in electrical contacts have revealed a contact resistance similar to copper. The composites are well suited for special applications, such as sliding electrical contacts, arc resistant switches, friction components and bearing/seal components.
