摘要

本文对两种不同涂层体系对低碳钢的防腐效果进行了比较研究。第一组样品涂上电弧热喷涂(EATS)沉积的铝底漆层，之后再涂上两层涂料，从而形成铝涂层系统;而第二组样品则采用传统的三层涂装系统(富锌底漆层)进行涂层处理。之后，所有样品都暴露在盐雾室中。对样品进行监测，记录其在腐蚀性盐水环境中的反应。通过扫描电子显微镜(SEM)、附着力和电化学腐蚀测试来表征涂层，并报告其性能(附着力、形貌和均匀性)的变化，这些变化与暴露时间有关。三层涂装系统在腐蚀条件下的保护时间几乎不符合制造商的要求;另一方面，铝漆系统通过延长保护时间取得了更好的效果。

Corrosion protection in saline environment of a carbon steel coated (aluminum & three-layer painting system) by eats

This paper presents a comparative study on corrosion protection of low-carbon steel coated with two different painting systems. The first set of samples was coated with an aluminum layer of primer deposited by Electric Arc Thermal Spray (EATS), after which two additional layers of paint were applied, thereby creating an aluminum-painting system; while the second set of samples was coated with the traditional three-layer painting system (zinc-rich layer of primer). Afterwards, all the samples were exposed to the salt spray chamber. The samples were monitored to record their reactions in the corrosive saline environment. Scanning Electron Microscopy (SEM), adhesion and electrochemical corrosion tests were performed to characterize the coatings and report changes in their properties (adhesion, topography and homogeneity), which are related to exposure time. The three-layer painting system barely complied with manufacturer claims on protection time under corrosive conditions; on the other hand, the aluminum-painting system yielded better results by prolonging protection time.

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
