Review of an Investigation of Ceramic Coatings for Metallic Turbine Parts and Other High-Temperature Applications
Abstract
Development is discussed of ceramic coatings of alumina, chromium oxide, cobalt oxide and their combinations to prolong life of alloys used in turbines and turbine blades or to enable alloys to withstand higher temperatures. Refractory frits of high thermal expansivity and various refractory admixtures were investigated. Some of the coatings withstood 500 hours at 1500 deg F with little visible change. Some alloys retained approximately their initial 0.2% offset yield value under conditions that almost completely corroded the uncoated alloy at 1350 deg F.
