摘要

The aluminized steel produced by chemical heat treatment forms a steady Fe_3Al alloy layer on the surface. A new aluminized technology is put forward in this paper. This aluminized method can form the Fe-28Al alloy layer with corrosion resistance on the surface of low carbon steel by electric induction heating. A remarkable characteristic of this new technology is the elimination of the brittle surface layer composed of the higher aluminum phases. This is accomplished by changing a series of technol- ogy parameters to control thickness, aluminum content and phase constitution in the Fe-Al alloy layer. The deformation resistance of the new aluminized steel is remarkably improved and service life increased two times. The phase structures of the Fe-Al alloy layer for this new aluminized steel are researched by means of electron probe microanalysis (EPMA), X-ray diffractometry (XRD) and transmission electron microscopy (TEM), etc.
