The corrosion behaviors of Fe_83-XC₁B₁₁Si₂P₃Cr_X (X = 0, 1, 2, and 3 at%) amorphous alloys in 0.1 M NaCl solution have been investigated by immersion and electrochemical tests. With the addition of Cr content from 0 to 3 at%, the corrosion rate of amorphous alloys gradually decreases from 2.57 × 10⁻¹ to 1.04 × 10⁻¹ mm·year⁻¹. The minor addition of Cr improves the corrosion resistance through the increase in the E_corr value, which makes it easy to reach a passive state and suppress pitting corrosion. The corroded morphology and products of amorphous alloys have been tested by scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The SEM/EDS analysis shows that the high corrosion resistance is due to the formation of dense and stable chromium oxide during immersion in NaCl solutions.

添加Cr对FeCBSiP非晶合金玻璃形成能力和腐蚀行为的影响

Fe _83-X C ₁ B ₁₁ Si ₂ P ₃ Cr _X（X = 0, 1, 2, 3 at%）非晶合金在0.1 M NaCl溶液中的腐蚀行为已经通过浸泡和电化学测试进行了研究。随着Cr含量从0原子％增加到3原子％，非晶合金的腐蚀速率从2.57×10 ^-1逐渐降低到1.04×10 ^-1  mm·年^-1。少量添加 Cr 通过增加E _corr提高耐腐蚀性值，这使得很容易达到钝化状态并抑制点腐蚀。通过扫描电子显微镜（SEM）和能量色散谱（EDS）测试了非晶合金的腐蚀形貌和产物。SEM/EDS 分析表明，高耐腐蚀性是由于在浸入 NaCl 溶液过程中形成了致密且稳定的氧化铬。
