ABSTRACT:
Aluminum alloys that are susceptible to damage by High Temperature Oxidation during solution heat treatment are protected against such damage by a coating containing sodium fluoroborate and/or other fluorine-containing-gas-generating material. The coating can be one suitable for lubrication during cold working of the substrate and can remain in place after the cold working to protect the substrate during subsequent heat treatment.
