Abstract

Methods for making an erosion resistant gas turbine engine compressor airfoil substrates coated with a diamond-like coating (DLC), wherein the coating airfoil substrates are protected from ingested abrasive particulates, may include the step of performing a hydrogen-free chemical vapor deposition (CVD) process by ablation of a graphite target in a vacuum. The DLC may be comprised predominantly of sp3 (tetrahedral) carbon, and may be devoid of detectable amounts of hydrogen.
