Abstract

Copper is protected against thermal oxidation by flame spraying it with a composition consisting of 70-90% Cr3C2 and 10-30% Al. The composition may be in the form of a loose powder or of a sintered rod and is preferably applied by a plasma torch. The layer so formed may be sprayed with Al2O3; ZrO2 stabilized with CaO, MgO or Y2O3; ThO2; MgO; MgO. Al2O3; Ca2ZrO3; ZrSiO4. A further sprayed layer of ZrO2 or Al2O3 may be applied.ALSO:Copper is protected against thermal oxidation by flame spraying it with a composition consisting of 70-90% Cr3C2 and 10-30% Al.
