Abstract:
1. A process of forming a coating system on a component, the process comprising: depositing a diffusion barrier layer on at least a surface region of the component, the diffusion barrier layer being capable of inhibiting diffusion of damaging elements therethrough; directly depositing an intermediate layer on the diffusion barrier layer, the intermediate layer comprising an erosion-resistant material, having a hardness that is greater than the diffusion barrier layer, and being deposited by a near-net-shape laser deposition process; and directly depositing an outermost layer on the intermediate layer, the outermost layer comprising an erosion-resistant material and having a hardness that is greater that the hardness of the intermediate layer; wherein the intermediate layer has a thickness of greater than the diffusion barrier layer and the outermost layer.
