Based on above results, reaction essence of <span style=\"color:red\">electrochemical</span> repairing for pitted 18-8ss electrode was proposed: during the periodic action of alternating current, recycle reactions take place on the <span style=\"color:red\">surface</span> and the pit area of pitted electrode, i. e., metal dissolves into cations (occurs at E-L) and form hydrous hydroxide, the hydrous hydroxide turns into metal oxide ( occurs at E-<span style=\"color:red\">H</span>), a 'bipolar mode' passive film forms and <span style=\"color:red\">Cr</span> content is increased in repaired passive film. At the pit area, enclosed state of the pit is destroyed by the perturbing effect of alternating current in 1.0 <span style=\"color:red\">M</span> <span style=\"color:red\">H2SO4</span> solution, thus the pit area will be repaired through above-mentioned process.
