FeCrAl/QAl7 aluminum bronze composite coating was prepared by the supersonic electric arc spraying technology. Microstructure and phase constituents of the composite coating were studied by means of OM, SEM and EDS analysis. The results show that the FeCrAl and QAl7 aluminum bronze composite coating has a typical layered structure which is composed of FeCrAl, QAl7 aluminum bronze flattened particles as well as alumina films between them. The oxidation resistance of arc-spraying FeCrAl /QAl7 aluminum bronze ...
