As a part of ongoing continuous improvement program, driven by lightweight and cost reduction strategies,Martinrea aims at reducing the use of nylon and Galfan on the steel tubes without compromising the qualityand still meeting OEMs warranty certification conditions. For this purpose we propose application of grapheneflakes on steel tubes as a protective coatings. However, there is still significant amount of characterizationwork and laboratory scale testing that should be performed for the assessment of the feasibility of thisapproach. In this work we will develop techniques to use graphene as a corrosion resistant material at anindustrial scale for low carbon steel brake/fuel tubes. We aim to a) characterize the graphene sheets producedby NanoXplore via mechanical exfoliation of graphite, b) develop methods to deposit graphene layers on top ofthe low C steel coupons, c) develop electrochemical methods to evaluate their corrosion resistance. The resultstransferred to Martinrea will contribute to understanding of properties of graphene and will lead to theimplementation of corrosion reduction strategies.

作为正在进行的持续改进计划的一部分，在轻量化和降低成本战略的推动下，Martinrea旨在减少钢管上尼龙和Galfan的使用，而不影响质量，并仍然满足OEM保修认证条件。为此，我们建议在钢管上应用石墨烯作为保护涂层。然而，仍然有大量的表征工作和实验室规模的测试，应该进行评估的可行性，这种方法。在这项工作中，我们将开发技术，使用石墨烯作为耐腐蚀材料在工业规模的低碳钢制动/燃料管。我们的目标是a）通过石墨的机械剥离表征NanoXplore生产的石墨烯片，B）开发在低碳钢试样顶部存款石墨烯层的方法，c）开发电化学方法来评估其耐腐蚀性。转移到Martinrea的结果将有助于理解石墨烯的性质，并将导致腐蚀减少策略的实施。
