Abstract

PURPOSE: To exactly prevent a hole corrosion into the aluminium base material by constructing a zinc diffusion layer, more reluctant of natural electrode potential than aluminium base material, on a skin layer of each part of the aluminium heat exchanger and by utilizing an action of sacrifice corrosion of the zinc diffusion layer on the base material surface.
