Research on Electrochemical Corrosion Properties of FSW Joints of H65 Brass Alloy
The electrochemical corrosion properties of welded joints of friction stir welding(FSW) were studied by measuring open potentials and polarization curves.The result shows that the corrosion resistance of welded joint is better than that of base material,because the microstructural refinement,homogenization and densification of joint reduce the electrochemical heterogeneity of grains and grain boundaries.
