Study on Surface Corrosion Resistance of Titanium Steel Clad Plate in Simulated Seawater
The surface corrosion resistance of different titanium steel clad plates in simulated seawater solution of 3.5% NaCl were compared and analyzed by polarization curve and alternating-current impedance methods.Results show that titanium layer of the clad plate is electrochemically corroded in 3.5% NaCl solution.A stable oxide film,which will improve the corrosion resistance,is formed on the surface of titanium layer during the electrochemical corrosion process;Both corrosion current density and corrosion rate of additive manufacturing clad plate are lower than those of explosive clad plate,implying better corrosion resistance;Corrosion resistance of the additive manufacturing clad plate can be enhanced by stress relieving annealing to eliminate internal stress.
