Abstract
A method of forming targets for cathodic arc deposition of alloy bond coats for turbine engines components consists of melting a base alloy containing aluminum and other metals, adding grain boundary strengthening alloy additions, and casting the melt to form a cylindrical billet that is subsequently sectioned into puck shaped targets. The grain boundary strengthening additions minimize intergranular fracture of the targets during high current operation of the arc coating process.
