Abstract Scope |
Regenerative oxygenated fuels that have a nearly neutral greenhouse gas life cycle, are promising for implementation with respect to socio-climapolitical efforts for environmental protection. However, there are challenges with regard to their compatibility with fuel-bearing components. Present study systematically investigates the material compatibilities of aluminum and iron alloys as well as selected coatings with automotive relevance. Depending on the composition and ageing state of the fuel, different material degradation behaviors are observed and may occur in some cases to a considerable extend. The degradation degree and morphological attack structure is strongly influenced by the blend proportion and composition of corrosion-stimulating impurities such as water or organic ions. Within the framework of a DoE-based experimental approach, the respective influencing factors are characterized phenomenologically and the underlying degradation mechanisms are investigated by means of electrochemical methods. An evaluation matrix can thus be used to identify critical scenarios and classify appropriate materials. |
