Abstract

Metal-matrix Cu–Ti–B nanocomposites were prepared by SHS method and their corrosion behavior was characterized by XRD, atomic force microscopy, polarization testing, and electrochemical impedance spectroscopy. Microhardness of synthesized composites attained a value of up to 544 H_V. The presence of BN, Cu₃Ti, and TiO phases leads to formation of Cu/BN, Cu/Cu₃Ti, and Cu/TiO galvanic pairs which accelerate corrosion.

SHS生产的Cu-Ti-B复合材料的腐蚀行为

摘要

通过SHS方法制备了金属基体Cu–Ti–B纳米复合材料，并通过XRD，原子力显微镜，极化测试和电化学阻抗谱对它们的腐蚀行为进行了表征。合成的复合材料的显微硬度达到高达544的一个值ħ _V。BN，Cu ₃ Ti和TiO相的存在导致形成Cu / BN，Cu / Cu ₃ Ti和Cu / TiO电偶对，从而加速腐蚀。
