Abstract
repair of turbine blades. Not only aspects relating to process and fabrication engineering but also materials engineering mechanisms are incorporated into this
technology. The process chain for the repair of turbine blades can be shortened
with this hybrid technology. The turbine blades considered here are components
of the high-pressure turbine and this paper therefore focuses on nickel-based
alloys. The nickel-based braze metal needed for the repair of turbine blades is
applied together with the hot gas corrosion protection coating by means of
thermal spraying and the coating system is subjected to a combined brazing and alitising process.

N2 - In this paper, a two-stage hybrid technology is developed for the near-net-shaperepair of turbine blades. Not only aspects relating to process and fabrication engineering but also materials engineering mechanisms are incorporated into thistechnology. The process chain for the repair of turbine blades can be shortenedwith this hybrid technology. The turbine blades considered here are componentsof the high-pressure turbine and this paper therefore focuses on nickel-basedalloys. The nickel-based braze metal needed for the repair of turbine blades isapplied together with the hot gas corrosion protection coating by means ofthermal spraying and the coating system is subjected to a combined brazing and alitising process.
