Microstructural properties of TZM alloys were characterized by SEM + EDS, XRD analysis and micro hardness tests. In corrosion tests, Tafel extrapolation and Electrochemical Impedance Spectroscopy (EIS) methods were used in solutions with different pH values (pH 4, pH 7 and pH 10). As a result of the studies, it is seen that depending on the amount of Zr added to the TZM alloy, different secondary phases are formed in the microstructure of Mo matrix and the grain boundaries. According to Tafel curves in pH 4, 7 and 10 solutions of TZM alloys with different Zr composition and electrochemical impedance spectroscopy (EIS) results. The highest corrosion resistance (in mm/year) was obtained in 0.09% Zr TZM alloy, the lowest corrosion resistance was obtained in 0.06% Zr TZM alloy. Moreover, the highest corrosion resistance was obtained at pH 7 and the lowest corrosion resistance at pH 10.eninfo:eu-repo/semantics/closedAccessTi-Zr-Mo alloysZr effectmicrostructurecorrosion behaviorsArticle10.1134/S20702051220202042-s2.0-851304104813642Q235658WOS:000799276200015Q3
