Cobalt is often employed in sintering processes for tungsten carbide as the binder phase because of its low melting temperature. The liquid phased cobalt binder provides the sintered product with higher density and toughness. The sintering process for WC will be much more difficult without cobalt or other lower melting-point metals as the

Nov 17, 2015 · Hydrogen Furnace Sintering is used widely as part of many powder metallurgy (PM) processes to create parts of extremely accurate size and uniformity. Stainless steel is common, but a other high-performance alloys, such as tungsten carbide and other alloys, also require high-temperature sintering in hydrogen.
