Modelling Corrosion Behavior of Friction Stir Processed Aluminium Alloy 5083 Using Polynomial: Radial Basis Function

摘要: Aluminium alloy 5083, widely used in marine applications, undergoes accelerated corrosion sea water due to the aggressive reaction of chloride ions with secondary phase particles and other intermetallics present matrix. The rate is also influenced by temperature difference between its environment. Friction stir processing (FSP) a recent solid state technique for improving surface properties metals alloys. In this study, an attempt has been made explore possibility resistance AA5083 FSP. FSP trials were performed varying tool rotation speed, traverse speed shoulder diameter tool, as per face centered central composite design. potential friction processed was studied using potentiodynamic polarization studies, at three different temperatures. Mathematical models based on polynomial—radial basis function developed study effect process parameters AA5083. resulted refinement grain structure, dispersion partial dissolution matrix, which increased alloy.
