摘要:
采用电弧熔炼结合真空甩带制备了Ni50Nb14Ta14P9Fe13非晶条带，通过XRD、SEM以及XPS分析了合金的微观结构，并采用差示扫描量热分析法、动电位极化曲线、电化学阻抗谱研究了退火对Ni50Nb14Ta14P9Fe13非晶合金耐蚀性能的影响。结果表明，铸态合金具有典型的非晶态结构。在1133和1213 K退火5 min后，合金均发生晶化，晶化程度随温度升高而增大，晶粒尺寸为10～32 nm。在65 ℃的32%HCl溶液中，铸态合金的耐蚀性能显著优于部分晶化试样（1133 K）和完全晶化试样（1213 K），自腐蚀电流密度为53.9 μA/cm2，约为部分晶化试样和完全晶化试样的25.6%和14.4%；其维钝电流密度为1.3 mA/cm2，约为部分晶化试样和完全晶化试样的33.3%和2.9%；晶化后其容抗弧半径显著减小。铸态合金的腐蚀速率最低，耐蚀性能最佳；而完全晶化后其腐蚀速率最高，耐蚀性能最差。本研究揭示了镍基非晶合金的晶化对其腐蚀行为的负面影响。
Abstract:
Ni50Nb14Ta14P9Fe13 amorphous ribbons were prepared by arc melting combined with vacuum strip spinning. The microstructure of the alloy was analyzed by XRD, SEM and XPS, and the effects of annealing on the corrosion resistance properties of Ni50Nb14Ta14P9Fe13 amorphous alloy were studied by differential scanning calorimetry (DSC), potentiodynamic polarization (PD) curves, and electrochemical impedance spectroscopy (EIS). The results indicate that the as-cast alloy has a typical amorphous structure. After annealing at 1133 and 1213 K for 5 min, the alloy undergoes crystallization, and the degree of crystallization increases with temperature, with a grain size range of 10~32 nm. In a 32wt% HCl solution at 65 ℃, the corrosion resistance property of the as-cast alloy is significantly better than that of the partially crystallized sample (1133 K) and the fully crystallized sample (1213 K), with a self-corrosion current density of 53.9 μA/cm2, which is about 25.6% and 14.4% of the respective value of the partially crystallized and fully crystallized samples. The passivation current density is 1.3 mA/cm2, which is approximately 33.3% and 2.9% of the respective value of the partially crystallized and fully crystallized samples. The capacitance arc radius significantly decreases after crystallization. The as-cast alloy has the lowest corrosion rate and the best corrosion resistance. Its corrosion rate is the highest and its corrosion resistance is the worst after complete crystallization. This study reveals the negative impact of crystallization on the corrosion behavior of the Ni-based amorphous alloy.
