Tungsten carbide - Wikipedia
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing shells and jewelry.

Abstract NiCrBSi/WC composite coatings containing various amounts of WC/W2C particles were laser cladded on low carbon steel substrate S235JR. Coatings were processed using two different laser systems, a 1 kW Nd:YAG and a 3.8 kW high power diode laser (HPDL). Coatings obtained with the Nd:YAG source demonstrate significant changes in the matrix microstructure with WC/W 2 C particle …

The extent of carbide precipitation depends upon carbon content, temperature and time at temperature. Sensitization in austenitic stainless steels occurs only in the temperature range 550-850 C. Rapid cooling of the steel through the sensitizing temperature range does not provide adequate time for the process of sensitizing to occur.
