Abstract
The disclosure provides a method for generating a metallic coating on a substrate using a mixture comprising a precursor compound typically of chromium oxide, a chemical agent typically comprising NH, and an inert transport fluid. The precursor compound and chemical agent are generally in the form of particulates having mean diameters less than about 100 microns, and the transport fluid is present in an amount sufficient to facilitate application of the mixture to a substrate. The mixture is applied to a substrate and the coated substrate is heated to a temperature exceeding the decomposition temperature of the chemical agent, generating a reducing gas typically comprising CO, H, and/or NH. In a particular embodiment, the precursor compound is CrO, CrO, CrO, or mixtures thereof, the chemical agent is urea, and the coated substrate is placed in a reactor having an inert atmosphere and subjected to a temperature of about 700° C. for about 5 minutes while maintaining an inert gas flow through the reactor.
