| Abstract: | Effect of solution treatment(solution temperature of 1080 ℃, holding time of 90 min) on corrosion resistance of the ZG40Cr25Ni20Si2 stainless steel was studied by means of potentiodynamic polarization, electrochemical impedance spectroscopy, neutral salt spray test and photoelectron spectroscopy. The results show that under this solution treatment parameter, after the solution treatment, the corrosion potential of the steel decreases, the corrosion current increases, the capacitance arc size is obviously lower than that of the as-cast one, and the corrosion resistance decreases. In neutral salt spray test, there is no obvious corrosion morphology in the as-cast and solution treated specimens within 96 h. After 144 h, the mass loss of the solution treated specimens is slightly larger than that of the as-cast one, and corrosion is more likely to occur. |
