Corrosion test of a nickel plating film
I am very new in plating industry. I produced Ni coating film on brass substrate. Would you please tell me how can I do corrosion test of my film. I heard about salt spray test and Dry/wet test but I don't know what should I do and why? I am looking for full testing procedure of corrosion test. Can anyone help me?Zia

The Metal Finishing Guidebook, and most other plating texts, will have a chapter on testing of plating, including corrosion testing of plating. The "salt fog test" conducted per ASTM B117 [affil link] is the most popular and recognized accelerated corrosion test, but all accelerated corrosion tests are rather unrealistic, especially this one, and the first question really is what kind of real-world performance you are in need of, and why.
