Coating systems are complex multi-component and dynamic, and critical to operational lifetime and safety of engineering materials. They typically fail due to delamination caused by electrochemical reactions at alloy-coating interfaces. Some of the inter-related parameters are shown schematically below. In this project we will improve mechanistic understanding of undercoating degradation processes with particular focus on surface dissolution, oxygen reduction and polymer degradation processes (in particular in response to by-products of oxygen reduction). We aim to deconvolute how the nature and concentrations of reactive species in the confined space between metal and coating play a role in polymer degradation

涂料系统是复杂的多组分和动态性，并且对工程材料的运营寿命和安全至关重要。它们通常由于由合金涂层界面的电化学反应引起的分层而失败。某些相互关联的参数在下面示意性地显示。在这个项目中，我们将提高对涂层降解过程的机械理解，特别关注表面溶解，还原和聚合物降解过程（尤其是响应降低氧气的副产品）。我们旨在否定金属和涂层之间的反应性物种的性质和浓度如何在聚合物降解中起作用
