Abstract
The corrosion behavior of Cr-C-deposited steel specimens, which were prepared from the Cr3+-based bath, was investigated in the 0.5 M H2SO4 solution. After electroplating, the deposited specimens were annealed at 300, 450, 600 and 700°C for 1 h. Based on the results of corrosion test, the corrosion resistance of as-plated and annealed Cr-C deposits has strongly related to the surface cracks. However, the corrosion resistance of 450°C-annealed Cr-C deposit could be obviously improved when the deposit was pre-polarized in the passive potential region. Annealed at 700°C, the corrosion resistance of Cr-C deposit is markedly raised owing to formation of Cr oxides on the crack surface during annealing.
