Gas turbines rely heavily on protective coatings to enable their operation at high temperatures. As the trend towards higher operating temperatures continues, improved coatings are constantly being sought. Current activities by academic institutions and equipment manufacturers include developing techniques such as cathodic arc and sputter deposition as much as researching new coating materials. Probably the biggest challenge faced by coating equipment manufacturers is anticipating the needs of the coatings market. To survive in this highly competitive environment, manufacturers need to be able to deliver proven technology at an affordable cost. This article will look first at the established methods of coating application in gas turbines including their advantages and limitations, then consider emerging alternatives and how they may be of benefit. Finally, the future equipment requirements will be considered that are necessary to keep the industry moving forwards technologically and economically.
