High Temperature Coatings For Industrial Gas Turbine Users.
High temperature coatings are used for protecting the high temperature turbine components from environmental attack due to oxidation and hot corrosion. These coatings have developed from simple aluminide coatings to complex overlay and duplex coatings. Over the past 15 years thermal barrier coatings, which lower the temperature of the metal, have become increasingly used in industrial gas turbines. This tutorial reviews all these coatings, how they provide protection, how they are applied, and their degradation. Included is a discussion of high temperature oxidation and hot corrosion. Also discussed is recoating and expected future developments of these coatings.
