a novel aromatic thermosetting copolyester can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene and other additives . surface treatments / coatings are key to improving wear performance and durability in a wide array of applications . the problems associated with use of liquid lubricants , hard / soft coatings are well known but only modest progress has been achieved due to lack of research on new material systems . these coatings were fabricated and tested as highly effective wear resistant coatings by blending atsp with ptfe and other tribologically beneficial additives . the main advantages of these polymeric - based coatings are their relatively low cost and simple substrate surface conditioning .
