Abstract

A coating system and processes by which the coating system can be deposited on a surface region of a component to be resistant to erosion, and particularly resistant to erosion caused by high moisture content environments. The coating system (14) includes a diffusion barrier layer (18), an intermediate layer (20) overlying the diffusion barrier layer (18), and an outermost layer (22) overlying the intermediate layer (20). The diffusion barrier layer (18) is capable of inhibiting diffusion of damaging elements therethrough. The intermediate layer (20) is an erosion-resistant material, having a hardness that is greater than the diffusion barrier layer (18), and being deposited by a near-net-shape laser deposition process. The outermost layer (22) is erosion-resistant material, having a hardness that is greater that the hardness of the intermediate layer (20). The intermediate layer (20) has a thickness of greater than the diffusion barrier layer (18) and the outermost layer (22).
