FIELD: metallurgy.
SUBSTANCE: invention relates to application of coating on substrate of heat-resistant nickel alloy and to article of said heat-resistant nickel alloy. Claimed article comprises the nickel allot substrate and modified underlying area and bulky area. The former contains the first composition while the latter includes the second composition other than the first one. Said modified underlying area includes at least one of reactive element or noble metal and features the depth smaller than approx 0.3 mcm measured in direction, on fact, perpendicular to substrate surface. Said modified underlying area is produced by deposition of the layer including at least one of reactive element or noble metal on substrate surface and introduction of said one of reactive element or noble metal in modified underlying area by ion bombardment.
EFFECT: production of heat-resistant nickel alloy article.
