<p><P>PROBLEM TO BE SOLVED: To provide a coated article (100), a coating film (104) for protecting an article (100), and a method for protecting an article (100). <P>SOLUTION: The article (100) comprises a metallic substrate (102) and a substantially single-phase coating film (104) disposed on the substrate (102), wherein the coating film (104) comprises nickel (Ni) and at least about 30 atomic% aluminum (Al). A gradient is formed in the Al composition in the coating film (104). The gradient extends from a first Al concentration level on the outer surface (106) of the coating film (104) to a second Al concentration level at an interface between the substantially single-phase coating film (104) and the substrate(102), wherein the first Al concentration level is greater than the second Al concentration level and the second concentration level is at least about 30 atomic% Al. <P>COPYRIGHT: (C)2004,JPO</p> |
