Abstract (en)
[origin: JPH02230902A] PURPOSE: To increase the resistance to corrosion and erosion of a vane of a heat engine by spraying a protective surface layer consisting of 6 to 15 wt.% of Si, the remainder being Al, onto a surface of a base material using a high- speed process with a particle velocity of at least 300 m/s. CONSTITUTION: A vane of a rotating heat engine consists of mainly a ferritic and/or ferritic-martensitic base material by applying a protective surface layer securing firmly thereon. The protective surface layer consisting of 6 to 15 wt.% of Si, the remainder being Al, is sprayed onto a surface of the base material using a high-speed process with a particle velocity of at least 300 m/s. Consequently, it is possible to increase the resistance to corrosion and erosion of the vane of the rotating heat engine.
