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.

Applications

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 ˚F (538˚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 for applications where impact or fretting wear is involved.

Classification

Coatings conforming to this specification are classified as follows: Type A: 7% Cobalt, 93% Tungsten Carbide Type B: 11% Cobalt, 89% Tungsten Carbide Type C: 14% Cobalt, 86% Tungsten Carbide Type A coating shall be supplied unless Type B or Type C is specified.

Safety - Hazardous Materials:

While the materials, methods, applications and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take the necessary precautionary measures to ensure the health and safety of all personnel involved.

Users who perform additional finishing operations on the coatings may produce particulate material, whether suspended in air or liquid, which requires safety-hazardous material considerations.
