Argonne National Laboratory has joined with the Allison Engine Company to explore the use of low-cost, oxide-based lubricant coatings to enable turbine-engine regenerator seals and cores to operate safely at temperatures up to 1100Β°C. Meeting this requirement is the key to the development of high-performance gas turbine engines for turbine-engine and hybrid-electric vehicles. Successful development and implementation of such coatings could substantially reduce fuel use, since a properly designed regenerator seal and core assembly can increase the fuel efficiency of a turbine engine by as much as 30%. The coatings may also contribute to a cleaner environment by reducing emissions. Argonne is testing coatings to enable turbine-engine regenerator seals and cores to operate at temperatures to 11oo"c.
Industry is interested in these coatings for hot-forming operations. The coatings are of interest because of their low friction and wear properties. They would be applied to dies and other components used in metal (and glass/ceramic) forming operation. The researchers are also exploring new alloys and coating compositions that can promote the formation of wear-resistant and lubricious oxides that could eliminate the use of time-consuming and expensive plasma-spray coatings.
