PS/PM300 high temperature solid lubricant coatings and composites

The Plasma Spray (PS)/Powder Metallurgy(PM) 300 are high-temperature solid lubricantsthat operate from cryogenic temperatures toover 1200 degrees Fahrenheit. The inventorsof the technology, Dr. Christopher Dellacorteand Brian J. Edmonds, used a NASA SpaceAct Agreement with ADMA, Incorporated, asthe vehicle for a commercialization project toreduce the cost of PS/PM300 by 50 percent.As a result, ADMA has licensed thetechnology and began producing commercialparts in 2002. A second license has beenawarded to Hohman Plating andManufacturing of Twinsburg, Ohio, andseveral other licenses are currently pending.PS300 coatings have replaced graphite andceramic parts in large steam turbine controlvalves in power plants. The Lincoln ElectricCompany is using thousands of PM300bushings in its high-temperature industrialovens to lubricate conveyor buckets and othercomponents. PM300 bushings replaced bronzebushings, which lasted only a month or less inthe 1000 degree Fahrenheit heat. LincolnElectric estimates it will save more than $1million over the first five years by using thesebushings. A spin-back benefit to NASA is thatthe agency now has a commercial productionsource for PS/PM300 material at a substantialcost reduction. NASA is currently evaluatingPM300 bushings for variable stator vanes ingas turbine engines and PS300 coatings on foilbearings for oil-free turbomachinery. Acomprehensive effort is now underway todevelop oil-free turbine engines for aircraft,with half the maintenance costs and 15% lowerweight than conventional oil-lubricatedengines.
