摘要: Abstract Titanium-zirconium-molybdenum (TZM) alloy was fabricated by using powder metallurgy and rolling techniques. Electrochemical corrosion behavior of the studied quantitatively potentiodynamic polarization scanning electron microscope. Effect different chloride ions concentrations on resistance electrochemical mechanism TZM investigated. Results show that pitting intergranular mainly occurs in sodium solution. Corrosion generates firstly form around second phase particles increases with corrosive media Cl − concentration increasing, then along grain boundaries defects. can effectively destroy passive film formed sample surface. As increases, rate until 1.0 mol/L decreases. exhibits good when is 0.5 mol/L or 1.5 mol/L.
