Development of Tribological Surfaces and Insulating Coatings for Diesel Engines

Developments in coating processes and evaluation techniques are discussed. Coatings in advanced engines comprise both those for wear resistance and low friction in high temperature advanced diesel engines and those for heat insulation to reduce heat losses or component temperatures. Advanced evaluation techniques used in these developments include hot wear procedures and radiant thermal cycling rigs. Engine testing of advanced components is in progress or is planned.
