  • Alumina forming coatings containing hafnium for high temperature applications
    Patent number: 4086391
    Abstract: Coatings are described which are particularly suited for the protection of nickel and cobalt superalloy articles at elevated temperatures. The protective nature of the coatings is due to the formation of an alumina layer on the surface of the coating which serves to reduce oxidation/corrosion. The coatings contain aluminum, chromium, and one metal chosen from the group consisting of nickel and cobalt or mixtures thereof. The coatings further contain a small controlled percentage of hafnium which serves to greatly improve the adherence and durability of the protective alumina film on the surface of the coating.
    Type: Grant
    Filed: September 1, 1976
    Date of Patent: April 25, 1978
    Assignee: United Technologies Corporation
