Abstract The corrosion behavior of vacuum diffusion welded component of H62 brass and TC4 Ti-alloy in 3.5% (mass fraction) NaCl solution for up to 24 h was investigated by means of immersion test, scanning Kelvin probe test, scanning electron microscopy attached with EDS and X-ray photoelectron spectroscopy. The results demonstrate that the weld seam width of the jointed H62 brass and TC4 Ti-alloy is about 25~30 μm, and the free corrosion potential of H62 brass is slightly higher than that of TC4 Ti-alloy at the initial stage of immersion test. However, with the prolongation of immersion time, the free corrosion potential of TC4 Ti-alloy turns to be higher than that of H62 brass, and the corrosion of the area of H62 brass, where closed to TC4 Ti-alloy is much more severe than that, where far away from the weld seam. The corrosion products of H62 brass after immersion test composed mainly of CuO, Cu2O, CuCl, CuCl2 and Cu(OH)2, while the scale on TC4 Ti-alloy composed mainly of Ti-oxides TiO2 and Ti2O3. The welded couple of H62 brass/TC4 Ti-alloy exhibits galvanic corrosion tendency in 3.5%NaCl solution, and the H62 brass acts as anode in the galvanic couple, which correspondingly underwent accelerated corrosion process.
