摘要	A graded (Ti,Al)N coating was deposited on 1Cr-11Ni-2W-2Mo-V stainless steel for aero-engine compressor blades by arc-ion plating(AIP). The microstructure and the morphology of the graded coating were investigated using electron-probe microanalysis (EPMA), X-ray diffraction and scanning-electron microscopy. The mechanical properties of the graded coating were investigated and it was found that the microhardness and the wear resistance were similar to those of the monolithic (Ti,Al)N coating, but much better than those of a homogenous TiN coating. In addition, the adhesive strength and the thermal-shock resistance of the graded (Ti,Al)N coating were much better than those of the monolithic TiN and (Ti,Al)N coatings. The oxidation tests were performed at 600 and 700 degrees C in air for 500 hr, and corrosion tests were carried out at 600 degrees C under the synergistic effect of water vapor and NaCl for 20 hr. Compared to pure TiN, it was found that due to the incorporation of aluminum, a protective layer rich in alumina was formed on top of the graded (Ti,Al)N coating, which greatly improved the oxidation resistance and corrosion resistance of the coating.
