Abstract
In order to achieve micro alloying of protective coatings for components such as turbine blades in a turbine engine, a base metal is splutter coated by deposition of a trace element to a desired proportion. A protective layer of the base metal is then applied over the trace element to prevent further reaction or oxidation of the trace elements. A coating consumable is therefore formed from the base metal and the trace element. The consumable may be produced immediately prior to coating of the component or may be inertly stored for subsequent use. The consumable is applied by laser deposition techniques whereby a coating is formed in the melting process.
