Type 1 hot corrosion furnace testing and evaluation.

Abstract

Furnace testing of superalloys and coating systems was conducted to determine if type 1 hot corrosion seen in operating gas turbine engines and burner rigs could be more simply reproduced. Furnace parameters were varied to determine optimum (most aggressive) values for a short term type 1 hot corrosion test. The results of these tests were ranked and compared to data available from a variety of burner rig tests and will serve as a base line for further type 1 hot corrosion materials and coating research.
