Hot Corrosion of Coated Superalloys in a Gas Turbine Environment.
Abstract
A program has been initiated to assess the effectiveness of commercially available coatings for nickel- and cobalt-base superalloys in withstanding a severe hot corrosion-erosion environment. The report describes the procurement of the nine coatings and includes data from inspection tests on the thirty-eight coating alloy combinations. Also included are calibration data on blade metal temperature distribution for specimens in the turbine environmental simulators. Data are also presented on the: Initiation of the hot corrosion tests at 1650 and 1800F; Stress-rupture and low-cycle fatigue tests on the uncoated alloys as-received and after a 500-hour thermal exposure cycle.
