Corrosion Behavior of Titanium Alloys Using Electrochemical Noise

Nowadays aeronautic industry is looking for lighter materials as Ti alloys because they resist higher stress than aluminium alloys and are lighter than steel alloys, saving of this way volume and weight. The EN technique was used to evaluate the corrosión behaviour of different Ti-alloys in H 2 SO 4 and NaCl at 3.5 wt% solutions. All samples presented mix corrosion being an indicative of the instability of passive layer generated in the...
