Abstract: Abstract:The basic situation of failure of equipments in coalfired power plant caused by wear and corrosion in operation process was expounded.The service condition of large key equipments and the wear and corrosion mechanism were analyzed. The application status of material for quickwear parts of key equipments was introduced. The application prospect of the wearresistant and anticorrosion materials was predicted. The result in this paper shows that the application of novel material and remanufacturing technology is of profound significance for energy conservation, consumption reduction, environment protection and development of environment economy.

Key words: Keywords:coalfired power plant, power generation equipment, wearresistant and anticorrosion material, novel material, remanufacturing technology
