Estimating Time to First Signs of Corrosion
Estimating Time to First Signs of Corrosion
(OP)
I have been tasked with investigating the "time to corrosion" of a new product which is currently in development. This unit will be enclosed by a sheetmetal cabinet and will be located outdoors. Previous units have been made of powdercoated cold-rolled steel but we have seen corrosion problems in installations in coastal areas.
Does anyone know of any references which correlate salt-spray testing (or other corrosion testing) with the "time to corrosion"? In other words, test "A" equals "B" years of service using material "C" with finishing "D"? I need to provide some documentation which supports that the combination of material and finish which is selected will last for the life of the product (15-20 years).

Lab testing will be very good at helping you rank various materials options. If you have real experience with some of them then maybe you will have an idea of the time scale.
