SBIR Phase I: Water-Based Corrosion Resistant Silicon Coatings

9860550 这个小企业创新研究第一阶段项目旨在设计和开发新的水性耐腐蚀硅涂料。 市场上有许多用于飞机的耐腐蚀涂层，其中大多数含有致癌的铬酸盐或挥发性有机化合物（VOC）。 由于这些化学物质对人类和环境的不良影响，使用这些含有致癌物和/或VOC的涂料是不可接受的。 因此，迫切需要开发含有环境安全成分的水性涂料，其具有上级耐腐蚀性能。 该公司已经发明了许多水基涂料，用于涂覆铝，碳钢和不锈钢基材。 在碳钢上的初步结果表明，这些涂层与金属的附着力是优异的，并且涂层在大气和水环境中具有耐腐蚀性能。 将测试涂覆基材的耐腐蚀性，最高可达500 ℃，还将进行盐雾试验（ASTM B-117和ASTM G85）。 将对这些涂层基材进行电化学阻抗谱（EIS）测量，以确定涂层的耐腐蚀性。 第一阶段和第二阶段研究的结果将为一系列金属基材提供防腐蚀涂层配方，这些涂层将是高效，低成本和环境友好的。 该水性涂料可用于汽车和柴油机的排气部件。 它们可用于从航空航天工业的铝到汽车工业的碳钢等各种基材。 它们也可用作化学工业反应容器中的耐腐蚀衬里。

9860550 This Small Business Innovation Research Phase I project aims to design and develop new water-based corrosion resistant silicon coatings. There are a number of corrosion resistant coatings for aircrafts available in the market and the majority of them either contain carcinogenic chromates or are volatile organic compounds (VOCs). The use of these coatings containing carcinogens and/or VOCs is not acceptable due to the ill-effects of these chemicals to humans and the environment. Therefore, there is an urgent need to develop water-based coatings containing environmentally safe ingredients, which have superior corrosion resistant properties. This firm has invented a number of water-based coatings to coat aluminum, carbon steel and stainless steel substrates. The preliminary results of these coatings on carbon steel show that the adhesion on the metal is excellent and the coatings possess corrosive resistant properties in atmospheric and aqueous environments. The coated substrates will be tested for corrosion resistance up to 500 C and the salt fog test (ASTM B-117 and ASTM G85) will also be carried out. Electrochemical Impedance Spectroscopic (EIS) measurements will be performed on these coated substrates to ascertain the corrosion resistant nature of the coatings. The results of Phase I and Phase II research will provide corrosion protection coating formulations for a range of metallic substrates and these coatings will be efficient, low cost, and environmentally benign. The water-based coatings can be used in the exhaust components of automobiles and diesel engines. They can be used for substrates ranging from aluminum for the aerospace industry to carbon steel for the automobile industry. They can also be used as corrosion resistant liners in reaction vessels of the chemical industry.
