Purpose: This specification covers the engineering requirements for applying tungsten carbide/cobalt coatings to metal parts by the detonation process and the properties of such coatings. Application: Primarily to provide a hard@ wear-resistant surface on metal partswhich do not operate in service higher than 1000??(540??. These coatings are not recommended for surfaces with deep vee-shaped grooves@ blind cavities@ narrow holes or sharp corners@ or where deformation of the basis metal may be expected. Higher cobalt content provides increased ductility for applications where impact or fretting wear is involved. Classification: Coatings conforming to this specification are classified by nominal cobalt content as follows: Type A - 9% Cobalt Type B - 11% Cobalt Type C - 14% Cobalt Type A coating shall be supplied unless Type B or Type C is specified by purchaser.
