Definitions
- the coating of the invention allows a significant gain in life while maintaining its role of abradable since its chemical composition remains the same.
- the molding is carried out by sintering or hot injection at a temperature of between 180 ° C. and 400 ° C.
- the hot injection is mainly adjusted according to the fluidity of the composition to be injected.
- the settings for the hot injection settings are:
