摘　　要：通过J-Quenching技术在低冷速(低于1000K/s)下制备出块体尺寸达2mm的Fe80P13C7非晶态合金。通过阳极极化曲线测试以及对样品在1mol/L的HCl溶液中浸泡后的腐蚀形貌的观察,对Fe80P13C7块体非晶态合金、非晶薄带以及晶态合金的电化学腐蚀行为进行了对比研究,结果表明,块体非晶的腐蚀性能优于非晶薄带和晶态合金。这可能是由于块体非晶态合金在制备过程中冷速较低,原子发生结构弛豫的时间更长,结合能增大,使得合金中原子与溶液中离子的反应速率减慢,从而提高了块体非晶态合金的腐蚀性能。Bulk amorphousFe80P13C7 alloy with a diameter up to Zmm can be preparect by means ot a raplo J- Quenching technique at a low cooling rate（lower than 1000 K/s）. A comparative study of the electrochemical corrosion behavior of Fe80P13C7 bulk amorphous alloy, melt-spun glassy ribbon and crystalline alloy had been performed by means of the testing of anodic polarization curve and the observation on the morphologies of the samples after corrosion in 1 mol/L HC1 solution. The results show that bulk amorphous alloy have a higher cor- rosion resistance than others. This could be accounted for the fact that the low cooling rate in the preparation process makes the time of atomic structural relaxation longer and results in the increase of atomic binding energy. So the reaction rate between the atoms in alloy and ions in solution slows down and the corrosion resistance of bulk amorphous alloy is improved
