Tribological properties of lightweight cubic boron nitride (c-BN) based composites under conditions of dry sliding and slurry erosion in sodium solution were studied. It was shown that c-BN based composite has a higher wear resistance as compared to WC-CoNi hard metals, TiC-Ni cermets and B4C-Al composites. This material was produced by SHS method followed by hot compaction. Binder phase consists of Ti, Fe, Cr, Ni and C. Within a stainless steel (FeCr25Ni11) binder phase, a secondary hard phase of TiC was found to be formed during production. Those ultra-fine sized spherical particles (up to 600 nm in diameter) were supposed to have a great influence on the tribological behavior of composite.
