A STATISTICAL ANALYSIS OF HOT-CORROSION TESTS OF SOME EXPERIMENTAL AND COMMERCIAL SUPERALLOYS
Abstract
The use of gas turbines in marine power plants depends in part on the development of superalloys which not only possess high temperature mechanical properties but also resist the corrosive effects of sea salt. A total of 137 experimental and commercial superalloys, both nickel and cobalt based, were exposed in burner rigs where controlled amounts of sea salt were added to the combustion products of sulfur-containing diesel fuel; test temperatures ranged from 1600 to 2125F; times ranges from 86 to 100 hours with 200 parts per million, and from 489 to 1100 hours with 5 parts per million salt. Corrosion was measured by recording both surface loss and maximum penetration.
