The Study of Automotive Aluminum Alloy Radiator Tank's Leakage

Abstract:

Contraposing radiators leak problem in a short time using, it is found existing S, Cl, O etc in leaking place by the analysis of the EDS spectrum. So the cause of the radiator tank leaks were written as follows: unqualified freezing liquid was used in water tank, or unqualified cooling water was added during the vehicle. Its high hardness and destructive Cl^-, S² ion and the oxygen enrichment conditions have stimulated and accelerated action on the pitting corrosion of aluminum alloy, lead to producing scale lateral in waterproof surface, then pitting corrosion and perforation failure were occurred early. The problem can be solved by improving the quality of the cooling fluid, or replacing aluminum alloy material in waterproof surface.
