Application of Ceramic Coatings to High Speed Diesel Engine Combustion ZoneComponents of Off-Highway Transport Vehicles

摘要

The use of thin, zirconia ceramic coatings on the combustion zone surfaces, i.e.piston crowns, cylinder heads, and exhaust valve faces and stems, of large and small bore high speed diesel engines were evaluated in test stand and in-service engine operation. Several different coating compositions were plasma sprayed on engines that propelled a towboat on the U.S. inland waterways and off-the-road ore carrying trucks with great success. The pre-alloyed, yttria stabilized
