摘要
Abstract
Microstnicture behavior is examined of welds of Al/Cu Dissimilar Metals plate of 4 mm in thickness prepared by Friction stir welding,the results indicated that the weld appearance quality is benign,and the two materials are mixed with each other,and the streamline structure resulted from plastic deformation is compact,and defect is prevented by rotation speed 1 050 r/min,traverse speed 40 mm/min and SA06 alloy in the advancing side and T2 plate in the retreating 3ide.Electrochemical corrosion resistance is researched in 3.5% sodium chloride solution. Anodic polarization curves reveal thai the corrosion potential of thermo -mechanically affected zone and heat affected zone of approaching to 5A06 alloy, which corrosion potential are lower and corrosion current are higher compared with basic materials are sensitive to corrosion, and tend toward to corrosion phenomena.关键词
