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.
RATIONALE AMS2435H stabilizes this document because this document contains mature technology that is not expected to change and thus no further revisions are anticipated. STABILIZED NOTICE AMS2435H has been declared "STABILIZED" by AMS Committee B Finishes, Processes and Fluids Committee. This document will no longer be updated and may no longer represent standard industry practice. Previously this document was reaffirmed non-current. The last technical update of this document occurred in April, 2001. Users of this document should refer any certification issues (e.g. exceptions listed on the certification report) to the cognizant engineering organization for their disposition. NOTE: In many cases the purchaser may be a sub tier supplier and not the cognizant engineering organization.
