Title: CORROSION PREVENTION METHOD FOR SURFACE OF ALUMINIUM-BASED MEMBER
Abstract:
The present invention provides a corrosion prevention method which is capable of sufficiently protecting the surface (in particular, the surface which is in contact with a gasket) of an aluminium-based member from corrosion, particularly when the surface of the aluminium-based member is sealed by the gasket. The corrosion prevention method for the surface of an aluminium-based member which forms, in conjunction with another member, a structure in which a gasket is sandwiched in a pressed state, is characterized in that a surfactant is adhered to the surface of the aluminium-based member.
