AMS2435H - Coating, Tungsten Carbide-Cobalt Coating, Detonation Process

Document Number: AMS2435H
Revision Number: H
Coating, Tungsten Carbide-Cobalt Coating, Detonation Process
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.

This coating has been used typically to provide a hard, wear resistant surface on metal parts which do not operate in service higher than 1000 degrees F (538 degrees C) but usage is not limited to such applications. These coatings are not recommended for surfaces with deep vee-shaped grooves, blind cavities, narrow holes or sharp corners, or where deformation of the base metal may be expected. Higher cobalt content provides increased ductility for applications where impact or fretting wear is involved.
