Abstract
Disclosed herein are methods for coating metal substrates, systems therefore, and articles made therefrom. In one embodiment, the method of coating a metal substrate comprises: disposing a metallic bond coating on the metal substrate, creating ions with a reverse polarity high frequency apparatus at a frequency of greater than or equal to about 2.5 kHz, roughening the surface with the ions to a subsequent average surface roughness of greater than or equal to about 5 μm, and disposing a ceramic coating on the metallic bond coating surface. The metallic bond coating had a surface with an initial average surface roughness of less than or equal to about 1 μm.
