Sealed hard coat corrosion resistance vs coating thickness


 

I am interested in hard coating 6061 for corrosion resistance and am planning a sodium dichromate seal. The hard coat will be according to Mil-A-8625 [link is to free spec at Defense Logistics Agency, dla.mil]F, Type III, Class 1. For dimensional tolerancing reasons I would like to keep the coat thin, but a having trouble finding a reference for corrosion resistance vs sealed hard coat thickness. It seems that if its sealed the corrosion resistance should not be affected by thickness.

Does anyone have any info?

Thanks!

Why hard coat? If corrosion resistance is your aim why not class I or II?
