THERMAL PROTECTION COATING FOR A TURBINE-ENGINE PART, AND A METHOD OF MAKING IT

摘要

A thermal protection coating, in particular for a turbine-engine part (12), the coating being deposited by thermal spraying onto the surface of the part (12) and including at least 80% by volume of hollow ceramic microbeads distributed in a metal alloy based on nickel or cobalt, it being possible for the coating to be deposited on a bonding layer (22) of metal alloy and for it to be covered in a layer (26) providing protection against erosion or against friction wear, or in a reflective layer that reflects thermal radiation.
