| Abstract: | The microstructure and the properties of anti-oxidization and hot-corrosion resistance of hot-dip aluminized Q235 steel was investingated.Microhardness tests showed that HV 0.1 hardness of aluminizing layer could reach 1000HV and the layer was found quite brittle.The microstructure and the microhardness of aluminizing layer were found changed obviously after annealing.High temperature Oxidization and hot-corrosion tests showed that the anti-oxidization properties of aluminized Q235 steel and 1Cr18Ni9Ti stainless steel were of the same level, but the former 's hot-corrosion resistance was superior to the latter 's remarkably. |
