Agar-based gel-electrolytes for corrosion diagnostic

在腐蚀诊断中，基于琼脂的凝胶电解质越来越多地被用作微创电解质变体。在当前项目的过程中，新的诊断概念正在开发中，例如双极电化学与含指示剂凝胶电解质的应用，这将使高合金材料的耐腐蚀性在几秒钟内进行非接触测试。另一个应用是利用碱性凝胶电解质的低腐蚀性对金属中可扩散氢进行灵敏的电化学检测，这将发展成为一种新型的金属部件h传感器技术。凝胶电解质与金属表面的相互作用已经在几个金属凝胶变体的项目中进行了研究，特别关注锌和锌上的腐蚀产物层。通过一种新的凝胶制造程序，凝胶电解质的范围将通过医学生物成分来扩展，从而模拟一个类似组织的环境，用于主动腐蚀植入材料，从而可以更真实地进行电化学和分析检查。

In corrosion diagnostics, agar-based gel electrolytes are increasingly used as minimally invasive electrolyte variants. In the course of the current project, new diagnostic concepts are being developed, such as the application of bipolar electrochemistry with indicator-containing gel electrolytes, which will enable contactless testing of the corrosion resistance of high-alloy materials within a few seconds. Another application uses the reduced corrosiveness of alkaline gel electrolytes for the sensitive electrochemical detection of diffusible hydrogen in metals, which is to be developed into a novel H-sensor technology for metallic components. The interaction of gel electrolytes with metal surfaces has already been investigated in the project on several metal-gel variants, with a special focus on zinc and corrosion product layers on zinc. By a new manufacturing procedure of the gels, the range of gel electrolytes will be extended by medical-biological components, whereby a tissue-like environment for actively corroding implant materials will be simulated and thus these can be examined electrochemically and analytically more realistically.
