Mechanical properties and corrosion resistance of metals are closely related to the microstructure characteristics of the material. The paper compares the results of these two sets of properties after investigating samples of base ductile iron and heat-treated samples of the base austempered ductile iron ADI. The basic material is perlite ferritic iron alloyed with copper and nickel. To test the corrosion rate of the base material ductile iron and the heattreated samples ADI, electrochemical techniques of potentiostatic polarization were used the technique of Tafel curves extrapolation and the potentiodynamic polarization technique.
