METHOD FOR COATING OF PARTS MADE FROM NICKEL-BASED ALLOYS Russian patent published in 2008 - IPC C23C24/00 C23C10/60

Abstract RU 2320774 C1

FIELD: chemical-thermal processing of metals and alloys in mechanical engineering.

SUBSTANCE: method involves providing chrome-aluminizing in powder mixture, followed by thermal vacuum processing for forming of β+γ'- phase structure with aluminum concentration of 16-18%; after thermal vacuum processing, siliconizing parts in powder mixture containing Si, NH₄Cl and Al₂O₃, followed by annealing for final formation of coating.

EFFECT: increased thermal resistance and sulfide corrosion resistance of coatings for parts.
