Abstract: The novel polar marine steel was heat-treated by the normalizing (N) and quenching and tempering (QT)
processes. The tribocorrosion coupling effect of the heat-treated steels under different applied potentials in simulated low
temperature seawater was investigated on a UMT-3 multifunctional friction and wear testing equipment equipped with
low temperature and electrochemical modules. The microstructures and worn surface morphologies of the steels after the
tribocorrosion tests were characterized by scanning electron microscopy (SEM) and white light interferometry. The
tribocorrosion mechanisms under different applied potentials were also explored. Results showed that, as the applied
potential increased, the average friction coefficients of the heat-treated steels decreased, while the wear depths, wear
weights, and corrosion currents increased. During the tribocorrosion tests, the open circuit potentials of the heat-treated
