SURFACE TREATMENTS FOR TURBINE COMPONENTS TO REDUCE PARTICLE ACCUMULATION DURING USE THEREOF |
摘要 |
A turbine engine component (10) includes at least one treated surface (14) wherein the treated surface has a surface roughness (Ra) of less than 12 microinches; and a hard coating (16) disposed on the treated surface, wherein the hard coating (16) is a nitride and/or a carbide material at a thickness of less than 50 microns formed using electron beam physical vapor deposition, cathodic arc evaporation, or magnetron sputtering. Also disclosed are methods for substantially preventing micropitting on a surface of a turbine engine component (10).
