Abstract
An automotive air conditioning system evaporator core is formed of an aluminum alloy and has a biocidal coating comprising a zinc layer deposited onto said aluminum alloy and an outermost elemental copper plate overlying said zinc layer. During air cooling operations, slightly acidic condensate accumulating on the surface reacts with the copper to form cupric ions that inhibit microbial growth.
