| Abstract: |
| The hot corrosion of turbine blades is one of the typical failures which occur in during operation in marine environment, and is also one of the main limits of blade service life. The characteristics of our marine environment and the corrosion characteristics of the turbine blades were analyzed. The mechanism and influencing factors of hot corrosion were discussed. It was concluded that the surface temperature of turbine blade, salt content of fuel gas, and the content of sulfur/vanadium in the fuel were the important factors of hot corrosion of turbine blades. The preventive measures for the hot corrosion of turbine blades were put forward from the aspects of material selection, coating application and maintenance. |
