摘要
A component subjected to one or more of rolling, sliding, abrasion and bending contacts is disclosed. The component has a surface and functionally graded material (FGM) thermally sprayed on the surface to form an FGM coating. The FGM coating has a thickness and a plurality of material compositions. The FGM coating also has a plurality of elastic modulus profiles. Each elastic modulus profile consists of a plurality of elastic modulii at a plurality of corresponding points within that thickness. The elastic modulii are in the range from about 28 Mpsi to about 60 Mpsi. Optionally, there is also a plurality of carbon content profiles.
