摘要:
An article (20) has a metallic substrate (100) having a plurality of recesses (104). A first coating is at least at the recesses (104) and has: a splatted layer (110); and a columnar layer (112) atop the splatted layer (110). A second coating is away from the recesses (104) and has: a columnar layer (112) atop the substrate without an intervening splatted layer (110).
