摘要： Disclosed herein are methods for coating metal substrates (12), systems therefore, and articles made therefrom. In one embodiment, the method of coating a metal substrate (12) comprises: disposing a metallic bond coating (14) on the metal substrate (12), 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 (18) with the ions to a subsequent average surface roughness of greater than or equal to about 5 µm, and disposing a ceramic coating (16) on the metallic bond coating surface (18). The metallic bond coating (14) had a surface (18) with an initial average surface roughness of less than or equal to about 1 µm.

摘要： A method of laser beam welding at least two adjacent superalloy components (12,14) includes (a) aligning the components along a pair of faying surfaces (18,20) but without a backing plate; (b) placing a superalloy shim (16) between the faying surfaces; (c) welding the components together using a laser beam causing portions of the superalloy components (12,14) along the faying surfaces (18,20) to mix with the superalloy shim (1b); and cooling the components (12,14) to yield a butt weld between the components (12,14).
