Abstract
PURPOSE: To prevent the rust formation and to remarkably improve anticorrosive property, by carrying out treatment for making passive state after carrying out electrolytic washing as pre-treatment and acid dipping of stainless steel etc. carried out fat removing treatment.
CONSTITUTION: Electrolytic washing and acid dipping are carried out as follows after carrying out fat removing treatment of stainless steel etc. by solvent, such as trichloroethane etc. That is, the electrolytic washing is carried out by the bath etc. composed of NaOH, NaCN used for electrolytic washing of steel and treatment is carried out at 25W40°C, 5A/dm3 for about 3W4 minutes. On the one hand, the bath composed of sulfuric acid, nitric acid, surface active agent. amine compound, is used for acid dipping and treatment is carried out at 60W70°C for 5W10 seconds. Next, water washing and treatment for making passibe state, are carried out after carrying out electrolytic washing and acid dipping as pre-treatment and then treated material is dried.
