Description
Summary:Salt spray experiments in NaCl solution at various pH values, chloride ion concentrations, and exposure times were used to assess the specimens corrosion resistance. Furthermore, an empirical correlation be created to forecast the corrosion rate of aluminium alloy AA2024 friction stir welds. The corrosion rate of friction stir welds of aluminium alloys was estimated using the design of experiments (DOE) method, which took into account the effects of pH, spray time, and ambient chloride ion concentration. The developed empirical relationship can be used to predict the corrosion rate of FSW AA2024 aluminium alloy welds with a 95 percent confidence level. At neutral pH circumstances, the corrosion rate was found to be lower. In acidic and basic conditions, the speed increased significantly.
