【Abstract】 In this paper, a simulating test of boiler tubes with supersonic-arc spraying coating for a power plant was introduced. The thermal shock resistance and anti-corrosion properties of FeCrAl, Ni30Cr70 and 45CT were examined. The results proved that the thermal shock resistance and anti-corrosion ability of FeCrAl and 45CT are much better than that of Ni30Cr70, and they can meet the demands of boilers in power plant.更多还原
