ABSTRACT:
A coating system is used on an engine component having an outer surface configured to be exposed to a first plurality of particles impinging against the outer surface at an angle within a first angle range and a second plurality of particles impinging at an angle in a second angle range. The system includes a bond layer overlying the engine component outer surface, a first erosion-resistant layer comprising a first material that is more resistant to erosion by particles impinging the component outer surface at an angle within the first angle range than by particles impinging within the second angle range, an interlayer overlying the first erosion-resistant layer, and a second erosion-resistant layer comprising a second material that is more resistant to erosion by particles impinging the component outer surface at an angle within the second angle range than by particles impinging within the first angle range.
