Abstract

The contact interaction of TiB2-SiC with alloys on the base of nickel is researched. It is established that small additives of chromium promote spreading of nickel on the surface of TiB2-SiC because chromium is surface-active element and promotes reducing surface tension of melt Ni-Cr. The micro-structure of interaction zone of TiB2-SiC with Ni-Cr alloys have been studied. The optimum compositions of metallic binders for composite materials on the base of titanium diboride-silumin carbide are determined.
