Abstract Scope |
In fuel-bearing components at elevated working temperatures, component lifetimes highly depend on the susceptibility to alkoxide corrosion. This corrosive degradation is unique with its spontaneous character and tremendously high material degradation rates after initiation. Present work showcases a novel high pressure-temperature micro-reactor which is able to conduct measurements with high to assess exact corrosion initiation times and reaction rates. Preliminary experiments were conducted to analyze corrosion initiation times and temperature dependability on surface conditions through a phenomenological approach. In addition, several biogenic-fossil fuel blends, including field relevant impurities were also tested for their corrosivity. Experiments were conducted in the framework of DoE and were analyzed with methods such as anova and factor elimination. Furthermore, the corrosion kinetics were extracted from experimental data points to develop a microscale simulation model. First results are able to successfully replicate corrosion kinetics and pit morphologies. |
