Corrosion rate of tin coating
Corrosion rate of tin coating
(OP)
Hi!
I'm trying to find information about the corrosion rate of tin coating, especially in seacoast atmospheres.
Does anyone know where I can find that information?
Thank you beforehand.

RE: Corrosion rate of tin coating
Depending on the quality level of the tin coating, I found a reference that provides corrosion rates of tin (this would be tin metal) in a marine environment. The corrosion rate over a 10 year exposure period was 9 mils/year (page 166, "Corrosion and Corrosion Control", by UHLIG). Keep in mind this is for tin metal and if a coating could be applied that is solid tin, you could probably use the corrosion rate listed above. Otherwise, a tin plate that is not properly applied or contains small pores will probably suffer the same fate as the tin plated can.
The key I believe is to have a dense layer of tin coating so that tin acts as the anode and corrodes versus the substrate material.
