摘要
研究了铁-乙-丙合金(乙含量为 0.1-9 wt%;丙含量为 0.2-4 wt%;铁含量为平衡)的机械性能和腐蚀性能。在室温下测定了合金的显微硬度和抗压强度、耐磨性和气蚀磨损性。在以下水溶液中采用重量法测定了腐蚀速率:0.5 M H2SO4、5 M H3PO4、0.8 M HNO3、1 M HCl、2 M CH3COOH、3 M NaCl 和 0.2 M Na2SO4。具有高硬度的 Fe-B-C 合金具有最高的抗磨料磨损性,而具有高抗压强度的合金具有最高的抗气体磨损性。在大多数酸性和中性介质中,由于腐蚀产物在样品表面的积累,Fe-B-C 合金的腐蚀速率随着时间的增加而降低。随着共晶菌落中共晶相和奥氏体相体积分数的增加,或者当结构中形成主晶相和包晶相界面时,腐蚀速率会增加。Fe-B-C 合金在氯化钠溶液中的耐腐蚀性最高,而在硝酸溶液中的耐腐蚀性最低。
Mechanical and Corrosion Properties of Fe–B–C Alloys
Mechanical and corrosion properties of Fe–B–C alloys (0.1–9 wt% B; 0.2–4 wt% C; Fe is balance) were investigated. Microhardness and compressive strength, resistance to abrasive, and gas-abrasive wear of the alloys were determined at room temperature. The corrosion rate was measured by gravimetric method in the following aqueous solutions: 0.5 M H2SO4 , 5 M H3PO4 , 0.8 M HNO3 , 1 M HCl , 2 M CH3COOH , 3 M NaCl, and 0.2 M Na2SO4 . The highest resistance to abrasive wear is shown by Fe–B–C alloys with high hardness and the highest resistance to gas-abrasive wear – by the alloys with high compressive strength. In a majority of the acidic and neutral media, the corrosion rate of Fe–B–C alloys decreased with increasing time due to the accumulation of corrosion products on the surface of the samples. The corrosion rate increased with an increase in the volume fractions of eutectic and austenite phases in the eutectic colonies or when interfaces between the primary and peritectic phases were formed in the structure. The Fe–B–C alloys demonstrated the highest corrosion resistance in the sodium chloride solution and the lowest one in the nitric acidic solution.
