Notes:
A new novel cored wire for producing FeCrAl/WC intermetallic coating by arc sprayingwas developed. The erosion wastage at high temperature of the coating was researched withdifferent impingement angles and temperatures. The results indicated that impingement angle andtemperature greatly affected erosion wastage of the coating. At the same time, when impingementangle was 90°, different temperature had a little effect on the erosion wastage. And whentemperature was 650°C, different impingement angle had a little effect on the erosion wastage too.As compared with water wall tube material (G20 steel) of power station boiler, the erosionresistance at high temperature of the coating was higher. The erosion resistance rate of the coatingwas 1.94~2.89 times of that of G20 steel when temperature was 650°C and particle was polygonalsilica. The results indicated that erosive condition of high temperature flue gas and fly ash mixturein boiler tube of pulverized coal fired power station could be solved with the FeCrAl/WC coating
