(57) : The present invention relates to a conditioning method of gas turbine engine components (e.g. compressor blades and 00 ----. vanes) for increasing fuel efficiency. The gas turbine engine components are plasma treated in a high vacuum environment to gener - I N ally reach a surface roughness (Ra) below 150 nanometers and in some cases below 25 nanometers. Then during the same process 1-1 C the components are coated using either a metallic or ceramic, hard, thin coating ranging from 100 to 3000 nanometers in thickness N depending on desired surface smoothness and non-fouling properties. The same treatment combined with a surface relaxation pro - O cess, which is part of a smoothing process, allows applying even up to 100 micrometers of hard coating without changes to high ,1 . cycle fatigue properties and overall performance. Improved surface smoothness of the components and enhanced non-adhesiveness of the contaminants advance the quality of the flow through the gas path and compressor efficiency.
