Abstract

In this study, the corrosion behavior of a Fe-Cr-Mo-B-C alloy, fabricated by spark plasma sintering of an amorphous alloy powder, in 3.5% NaCl solution was analyzed. Electrochemical impedance spectroscopy and potentiodynamic polarization are techniques which were used for electrochemical performance estimation of samples and the results were further compared with conventional alloys: 1080 carbon steel and 304 stainless steel. Corrosion surface products were characterized through Scanning electron microscopy, Energy dispersive x-ray spectroscopy and X-ray photoelectron spectroscopy. Specimens sintered at 800℃ (S1-800) had achieved 94% densification approximately while the sample sintered at 900℃ (S2-900), had densified more which was 98% approximately. S2-900 had better corrosion resistance than S1-800 while in comparison to conventional alloys; it was inferior to 304 stainless steel. It was concluded that the increase in density of sintered samples favoured the formation of more uniform surface products and enhanced the formation of the passive chromium oxide (Cr2O3) layer.

火花等离子烧结Fe-Cr-Mo-B-C合金在3.5% NaCl溶液中的腐蚀
研究了火花等离子烧结非晶合金粉末制备的Fe-Cr-Mo-B-C合金在3.5% NaCl溶液中的腐蚀行为。利用电化学阻抗谱和动电位极化技术对样品的电化学性能进行了评价,并与常规合金1080碳钢和304不锈钢进行了比较。通过扫描电镜、x射线能谱和x射线光电子能谱对腐蚀表面产物进行了表征。800℃(S1-800)烧结试样致密化率约为94%,900℃(S2-900)烧结试样致密化率约为98%。与常规合金相比,S2-900的耐蚀性优于S1-800;它不如304不锈钢。结果表明,烧结试样密度的增加有利于形成更均匀的表面产物,促进了被动氧化铬层的形成。
