A. Hi Rajasekharan.
If salt spray numbers rather than real world viability are the concern, then paint is usually the way forward. Epoxies if the application is not outdoors; polyesters or preferably kynar type if outdoors. Electrocoat priming before painting will contribute in any case, and help a great deal if topcoat coverage is poor anywhere.

Please tell us the full situation please because answers to abstract questions will often mislead.
Luck & Regards,

A. Conducted tests: The coating with pore-free chrome withstands 1000 hours SST (5% NACL). This was the requirement of the customer for the chrome coating of the gate valves of the main gas pipelines.
