In SRC & # 171; Kurchatov Institute & # 187; - TsNII KM & # 171; Prometheus & # 187; a new approach to the creation of porous functional ceramic coatings on the steel surface is proposed due to the integrated use of the methods of low-temperature heterophase transfer and microarc oxidation. The adhesion of the coating to the metal is at least 60 MPa. The intermediate layer of the coating contains intermetallic compounds of the nickel - aluminum system and provides the mechanical strength of the coatings during operation at temperatures above 750 ° C. The possibility of deposition of catalytically active substances with promoters on the surface of porous coatings from solutions of their salts or hydroxides with subsequent decomposition as a result of heat treatment is shown, as well as the possibility of deposition of metals into the pores of the MAO coating by the example of nickel.
