Hot Corrosion of Coated Superalloys in a Gas Turbine Environment.

Abstract

A program was initiated that will assess the effectiveness of commercially available coatings for nickel- and cobalt-base superalloys in withstanding a severe hot corrosion-erosion environment. In addition, the influence of the coating on the stress rupture and fatigue properties will be measured. The recoat potential of selected coatings will be assessed after extended temperature exposure by stress rupture testing. Six nickel-base and two cobalt-base superalloys were ordered. Receiving inspection and baseline stress rupture tests on the uncoated specimens were initiated. (Author)
