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.
