US-Egypt Cooperative Research: New Coating Formulations Containing Natural Inhibitors for Steel Corrosion Control

0317586 Ludwick描述：该奖项旨在支持亚拉巴马塔斯基吉大学地质化学系Adriane Ludwick博士和埃及亚历山大大学化学系Esam Ibrahim Al-Hanash博士之间的合作研究项目。 研究人员将研究新的聚合物防腐配方，以及中东地区的草药和/或海水中的绿色藻类提取物。 将检查钢结构的表面处理。将通过实验室加速试验（如交流阻抗和盐雾试验）以及通过在埃及亚历山大港浸泡样品进行现场研究，对含有天然提取物的聚合物涂层进行性能评估。 这项工作是基于塔斯基吉大学和亚历山大大学之前的成功合作，其中使用从藻类中提取的化合物开发了一种防腐蚀涂层。目前正在通过在埃及举办由最终用户参加的讲习班传播这一合作的成果。适用范围： 含防腐添加剂的有机聚合物用作涂层材料，以增强土木工程建筑、埋地管道和海洋结构等钢结构的防腐保护。这些涂层可用于复杂形状的截面，如弯管、阀门和三通截面。 该项目将受益于这两个项目主管的互补技能，以及他们的大学之间目前建立的良好联系。 美国PI在该领域具有开发含有藻类的清漆的经验，该清漆已被证明在海洋环境中有效。 这两名科学家将把该项目的成果传播给最终用户。 年轻教师参与拟议的项目将提高未来国际合作的潜力。 该项目将向学生介绍腐蚀速率和机制的电化学评估的现代技术，以及抑制钢腐蚀的天然有机方法的类型。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

0317586LudwickDescription: This award is to support a cooperative research project between Dr. Adriane Ludwick, Chemistry Department of Geology, Tuskegee University, Tuskegee, Alabama and Dr. Esam Ibrahim Al-Hanash, Chemistry Department, Alexandria University, Alexandria, Egypt. The investigators will study new anti-corrosion formulation of polymer together with extracts from herbs indigenous to the Middle East area and/or green algae available in seawater. Surface treatment of steel structures will be examined. The performance evaluation of the polymer coatings containing the natural extracts will be done by means of laboratory accelerated tests such as ac impedance and salt spray fog test, as well as by means of field studies through immersion of samples in the Alexandria Harbor of Egypt. This work is based on a previous successful collaboration between Tuskegee University and Alexandria University in which an anti-corrosion coating was developed using compounds extracted from algae. The results of that collaboration are currently being disseminated through workshops in Egypt attended by the end-users. Scope: Organic polymers with anti-corrosion additives are used as coating materials to enhance the corrosion protection of steel structures such as civil engineering constructions, buried pipelines and marine structures. These coatings can be used in complex shaped sections such as bends, valves and tee sections. The project will benefit from the complementary skills of the two PIs, and from the currently well-established links between their universities. The U.S. PI has experience in the field having developed a varnish containing algae that has proved effective in marine environments. The results from this project will be disseminated by the two scientists to end-users. The involvement of younger faculty in the proposed project will enhance the potential for future international collaborations. The project will introduce students to modern techniques of electrochemical evaluation of corrosion rates and mechanisms, and to the types of naturally occurring organic means for inhibiting corrosion of steel. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
