Effects of Iron on the Corrosion Resistance of Titanium

Iron oxide deposits on the surface of titanium also have a passivating effect. Galvanic coupling of titanium and iron can lead to accelerated corrosion of the iron and, in some environments, to hydrogen embrittlement of the titanium. The magnitude of the effect is dependent on surface area ratios and the characteristics of the environment.
