Abstract
This work investigated the service performance of nickel-coated manganese steel in both normal 
high-chloride (clean) and low-sulphate high-chloride (polluted) seawater environments (typical 
offshore oil and gas production environments). Structural manganese steels coated with nickel 
together with the control were tested for corrosion characteristics using the weight loss method. 
It was found that the nickel coat was able to resist corrosion overtime via spontaneous formation 
of passive oxide films at ambient temperatures. Analysis of resulting corrosion rates underscored 
the viability of nickel coating at inhibiting severe corrosion owing to the harsh chloride- and 
sulphate-containing seawater typical of the oil and gas production environments.
