Abstract: Titanium and titanium alloys have excellent corrosion resistance and high temperature resistance, and are widely used in impellers and furnaces of wave soldering equipment. The corrosion resistance of TA1 and TA0 in 250 ℃ Sn37Pb soft solder and 300 ℃ SAC305 soft solder was studied based on static and dynamic brazing metal corrosion experiments. The electrochemical polarization curve and AC impedance test results show that the self-corrosion current density of TA0 is lower and the radius of capacitive arc is larger, and the passivation film of TA0 is more dense and stable. The corrosion rate of TA1 in the static molten 250 ℃ Sn37Pb brazing metal is larger, and the corrosion resistance of TA0 is better than that of TA1, mainly due to the lower O content in TA0 and more stable of the passivation film. In the static molten SAC305 brazing metal at 300 ℃, the corrosion rate of TA0 is smaller, and the corrosion resistance to the brazing metal is stronger, mainly due to the lower Fe content of TA0 and the lower generation content of FeSn₂. In the dynamic SAC305 brazing metal, the increase of the rotational speed accelerates the corrosion of titanium alloy, due to the erosion and corrosion of the brazing metal, the corrosion rate of titanium alloys in the dynamic brazing metal is higher than that of the static brazing metal. The corrosion rate of TA0 is less than that of TA1, and the corrosion resistance is better.
