Corrosion of multi material designsThursday (09.11.2017) 15:20 - 15:40 Part of:
Multi material designs especially dealing with lightweight materials such as Magnesium and Aluminum in combination with CFC can lead to severe galvanic corrosion. Electrochemical polarization curves can be used as an investigation and forecast tool to check the risk of galvanic corrosion of different material combinations. Therefore the advantages and possibilities of this method to describe the corrosion behavior (free corrosion potential, passivity, …) are introduced. Finally some approaches to avoid galvanic corrosion will be mentioned.
