polishing methods; therefore, it is expected to improve surfaces compared with existing mechanical processing methods. In this work, the effect of pulse time on corrosion resistance rate against synthetic... mm on the specimens. Then, the test pieces were soaked in cells to test the corrosion resistance rate. A 0.05989 mol/L NaCl solution was used to simulate seawater. The oxygen removal period in the cell......
