The aim for my project is to understand both the mechanisms and parameters behind the cut edge corrosion & corrosion resistance of new grade galvanised steel substrates under varied intense conditions, typically of C4/C5 grade exposure environments with variations such as moisture, pH, and salt content. The reasonings behind this are to combat the ever-growing need for sustainability in our modern world as it becomes ever more necessary to increase the lifetime of the materials produced to both save material costs and reduce the need for the mass production of new replacement materials. Primary aspects we will aim to analyse are as follows; Investigating how the different and new types of galvanizing alloys corrode at cut edges with and without protective organic coatings, how different coating formulations such as binding chemistry can influence cut-edge corrosion, What different severity environmental parameters influence the cut-edge corrosion of different types of galvanized steel. And finally, How to improve the inhibition of cut-edge corrosion by a protective organic coating.

我的项目的目的是了解新等级镀锌钢基材在各种剧烈条件下（通常是具有湿度、pH 值和盐含量变化的 C4/C5 级暴露环境）的切割边缘腐蚀和耐腐蚀性能背后的机制和参数。其背后的原因是为了应对现代世界对可持续发展日益增长的需求，因为越来越有必要延长所生产材料的使用寿命，以节省材料成本并减少大规模生产新替代材料的需求。我们要分析的主要方面如下：研究不同类型和新型镀锌合金在有或没有保护性有机涂层的情况下如何在切割边缘腐蚀，不同的涂层配方（例如粘合化学物质）如何影响切割边缘腐蚀，哪些不同严重程度的环境参数影响不同类型镀锌钢的切割边缘腐蚀。最后，如何通过保护性有机涂层提高对尖端腐蚀的抑制作用。
