Titanium Alloys in Hydrochloric Acid

Project example electrolytic corrosion
• Electrochemical corrosion tests
• Materials selection


Design of chemical plants and testing their materials durability
Here: Investigation of the corrosion behaviour of titanium alloys in concentrated hydrochloric acid at elevated temperatures
Considering the influence of the specific alloy composition on the corrosion behaviour of the material


Electrochemical measurements in an aggressive test medium according to customer specifications and determination of relevant electrochemical parameters such as free corrosion potential or passive current density
SEM / EDX investigations for surface analysis and evaluation of the corrosion mechanism

Customer Benefit

Determination of a safe corridor for the operation of the plant under the given aggressive conditions
SEM analysis reveals the dissolution of the titanium matrix if secondary phase precipitations are present and acting as local cathodes
