摘      要：The extruded AZ61A magnesium alloy plates of 6 mm thickness were butt welded using friction stir welding（FSW） *** corrosion behavior of the welds was evaluated by conducting immersion test in NaCl solution at different pH value,immersion time and chloride ion *** empirical relationship was established incorporating pH value,immersion time and chloride ion concentration to predict the corrosion rate of friction stir welds of AZ61A magnesium alloy at 95% confidence ***-factor,five-level central composite rotatable design was used to minimize the number of experimental *** surface method was used to develop the *** results show that the corrosion resistance of AZ61A magnesium alloy welds in the alkaline solution is better than that in the acidic and neutral solutions,moreover,low corrosion rate is found at low concentrated solution and longer exposure time,and the corrosion morphology is predominantly influenced by the distribution of β-phase.
