摘要:
采用真空热压烧结工艺制备了FeCu30(质量分数)合金胎体，利用SEM、XRD和硬度计分别研究了胎体的金相组织、物相结构和硬度，采用电化学工作站对比分析了烧结胎体在3.5% NaCl溶液中浸泡不同时长后的阻抗和极化曲线，进而探究胎体的耐蚀性能。结果表明：在23 MPa、850 ℃下烧结胎体的整体质地均一，致密度达96.71%，硬度值约为178 HV；胎体主要由Fe、Cu和少量的Fe3O4及FeO相组成。此外，随着烧结胎体在溶液中预浸泡时长(0、0.5和1 h)的增加，电化学腐蚀电位增大，最大为–0.80 V，而腐蚀电流密度降低，最小为9.16×10–6 A?cm–2。
Abstract:
FeCu30 (mass percent) alloy was prepared by vacuum hot pressing sintering technique. The microstructure, phase constitution and hardness of the FeCu30 alloy were studied by SEM, XRD and Vickers hardness tester, respectively. Moreover, the impedance and polarization curves of the sintered alloy with different pre-soaking treatments (0, 0.5 and 1 h) in 3.5% NaCl solution were comparatively analyzed by electrochemical workstation, and then the corrosion resistance of FeCu30 alloy was explored. The results show that the microstructure of the sintered alloy is perfectly uniform at 23 MPa and 850 ℃, the density is as high as 96.71%, and the hardness value is about 178 HV. Besides, the alloy is mainly composed of Fe, Cu and little Fe 3O4 and FeO phases. With the increasing of the pre-soaking time (0, 0.5 and 1 h) in 3.5% NaCl solution, the electrochemical corrosion potential increases to –0.80 V and the corrosion current density decreases to 9.16×10 –6 A?cm–2.
