Abstract:
Objective:To evaluate the anti-corrosion property of Ti-Zr alloy fabricated by laser solid forming technic in artificial saliva.Method:The corrosive behavior of Ti-Zr alloy fabricated by laser solid forming was studied by potentiadynamic polarization technique in artificial saliva at 37 ℃(pH=6.8).Ti-Zr alloy formed by casting was applied as the control.With the polarization curves given by the electrochemical corrosive measure system and the picture of corrosive plane given by SEM, the corrosive property of the Ti-Zr alloy were analyzed.Results:Ti-Zr alloy fabricated by laser solid forming showed more relatively positive corrosion potential, smaller corrosion current density and lower passive potential, and did not show any evidence of corrosive phenomena.Conclusion:Ti-Zr alloy fabricated by laser solid forming has good corrosive resistance in oral circumstances.
