Improving the corrosion resistance of friction stir welding joint of 7050 Al alloy via optimizing the process route

The macro-galvanic effect in friction stir welding (FSW) joints is contributive for accelerating the localized corrosion of 7xxx aluminum alloy weldment. A process route, solid solution treating→FSW→T76 ageing (SSW-T76), was developed to weak the macro-galvanic effect. The microstructure and corrosi...
