Study of the corrosion resistance of Cu-based amorphous ZrCuAlSi and CuZn alloys (R-8132)

Amorphous solids are non-crystalline materials whose atomic packing does not exhibit long-range order in contrast to crystalline alloys with long-range order. Thus, the aim of the present project is to produce a Cu-based metallic glass composition and a crystalline alloy to completely characterize both from the mechanical point of view, as well as from the electrochemical point of view. The addition of minor elements to this composition in order to improve its properties and to understand the underlying mechanism driving the corrosion processes will be analysed. Therefore, this research project aims to improve the knowledge on the physical and chemical aging effects on metallic glasses and, afterwards, to apply this knowledge to develop new advanced materials with improved performance and reliability for specific applications such as structural maritime alloys for off-shore applications.
