| Abstract: |
| Based on the service characteristics of aircraft engines in the marine environment, and according to the working conditions of the engine blades under different climatic conditions in the ocean/nearshore area, the failure mechanism of the cold-end blades of the engine under the combined action of corrosion and erosion was summarized. The related research on protective coatings of engine blades in marine environment is generalized and introduced, and the design concepts and performance of different protective coatings of blades are epitomized. The protective coatings of aero-engine blades are mainly one-or multi-element metal nitride coatings and bonding coatings of metal phase and ceramic phase now. The two types of coatings are designed to improve the strength-to-toughness ratio and wear and corrosion resistance of the coating by controlling the phase content in the coating. |
