Abstract
This study aims at investigating the effect of a fusing treatments on anti-corrosion characteristics of Ni-based self-flux alloy coating. Ni-based coatings were fabricated by flame spray process on steel substrates, and fusing treatments were performed using a vacuum furnace at <TEX>$800^{\circ}C$</TEX> <TEX>$900^{\circ}C$</TEX>, <TEX>$1000^{\circ}C$</TEX> and <TEX>$1100^{\circ}C$</TEX>. After fusing treatments, corrosion tests were carried out using potentiostat/galvanostat at solution with pH 2 and pH 6. Corrosion potential(Ecorr) and corrosion current density(Icorr) could be analyzed from polarization curve. Fusing-treated coating at <TEX>$1100^{\circ}C$</TEX> showed more favorable anti-corrosion characteristics than as-sprayed coating. Anticorrosive effect of fusing-treated coating at solution with pH 2 was relatively greater than at solution with pH 6. Fusing-treated coating at <TEX>$1100^{\circ}C$</TEX> showed the most excellent anti-corrosion characteristics.
