METHOD OF OBTAINING COATINGS THAT PROTECT AGAINST HIGH-TEMPERATURE OXIDATION

摘要

The invention relates to a method of obtaining coatings that protect against high-temperature oxidation, based on MCrAlY, wherein M is selected from the group containing Ni, Co or Fe or the alloys thereof, and comprises the thermal spraying of MCrAlY-based powders using high-frequency pulsed detonation (HFPD) techniques. Optionally, a high-density ceramic layer can be deposited on the MCrAlY layer using high-frequency pulsed detonation (HFPD) techniques.
