HEAT-PROTECTIVE COATING FOR A TURBINE ENGINE PART, AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a heat-protective coating, in particular for a turbine engine part (12), which is deposited by means of thermal spraying onto the surface of the part (12) and includes at least 80 vol % of hollow ceramic microbeads distributed in a nickel or cobalt metal alloy, said coating being depositable onto a metal alloy bonding layer (22) and coated with a layer (26) for protecting against erosion or wear due to rubbing, or with a layer for reflecting heat radiation.
