英文摘要	The Fe-15Mn-5Si-14Cr-0.2C amorphous composite rod sample added with and without rare earth elements of Ce, Dy and Ce+Dy were prepared using industrial purity raw materials treated by the coating agent (CaO-Fe2O3-SiO2). The effects of Ce, Dy and Ce+Dy rare earth elements addition on the microstructure were studied by XRD and TEM. The electrochemical workstation three-electrode system was used to test the corrosion behavior of the sample in 1 mol/L HCl and 1 mol/L NaOH. The results show that the microstructure of the alloys added with rare earth elements is amorphous composite matrix with the undercooled austenite phase CFe15.1 and the ferrite phase Fe-Cr. The corrosion resistance of the sample with 1 wt% Ce in HCl and NaOH is optimum. The self-corrosion potential in HCl is -0.16205 V, the self-corrosion current density is 7.6999 x 10(-8) A.cm(-2), and the polarization resistance reaches 9.5774x10(8) Omega.cm(2). In NaOH, the self-corrosion potential and self-corrosion current density is -0.1839 V, 1.7453x10(-8) A.cm(-2), respectively, and the polarization resistance value is 7.1574x10(8) Omega.cm(2). The corrosion resistance is obviously better than that of 304 stainless steel. It is a corrosion-resistant material with great potential.
