Estimating the term…
A method for forming a protective coating on a substrate comprising, applying a bond coating to the substrate, the bond coating having a first surface roughness, ionizing an inert gas which flows into the surface of the bond coating so as to impart a second surface roughness to the bond coating greater than the first surface roughness, wherein the inert gas is ionized and caused to flow into the surface of the bond coating by a reverse polarity current supplied to an electrode which removes at least one electron from the inert gas, and applying a top coating to the bond coating. Additionally, a method for preparing a surface to receive and adhere to a coating comprising roughening the surface to create a micro-roughening network on the surface. In addition, a method of improving strain tolerance and cyclic spallation life of a protective coating.
