Abstract
A method for applying a functionally gradient coating on a component, having a surface and subjected to one or more of rolling, sliding, abrasion and bending contacts, including the step of thermally spraying a functionally gradient material (FGM) on said surface that forms an FGM coating, said FGM coating having a thickness, a plurality of material compositions and 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.
