Abstract:
A process of depositing a multi layer coating containing a metal or a metal alloy on at least a portion of an article surface comprising:depositing by electroplating at least one electroplated metal or metal alloy layer on at least a portion of said article surface;subjecting said article having said at least one electroplated layer on at least a portion of its surface to pulses of air to dry said article surface and remove any liquid spots therefrom; anddepositing by chemical vapor deposition at least one layer selected from the group consisting of refractory metal and refractory metal alloy and at least one layer selected from the group consisting of refractory metal compound and refractory metal alloy compound on at least a portion of said electroplated layer, wherein said refractory metal compound is selected from the group consisting of nitrides, carbides, carbonitrides, oxides and reaction products of said refractory metal, oxygen and nitrogen, and wherein said refractory metal alloy compound is selected from the group consisting of nitrides, carbides, carbonitrides, oxides and reaction products of refractory metal alloy, oxygen and nitrogen.
