SBIR Phase I: Ultra-Low Wear Coatings Based on a Novel Family of Aromatic Thermosetting Copolyesters

该小型企业创新研究（SBIR）第一阶段项目旨在开发芳香族热固性共聚酯（ATSP）系统，并将其加工成高效耐磨涂料。表面处理和涂层是在各种应用中提高耐磨性和耐久性的关键。在这个项目中，不同的ATSP粉末混合物将进行研究。 将在金属基材上制备ATSP/PTFE共混物涂层（使用烧结）。 将在工业相关条件下对这些涂层进行摩擦学试验。 还将探讨ATSP粉末混合物的初步喷涂。该项目的更广泛/商业影响将是为空调和制冷压缩机等机械设备提供超低磨损涂层的潜力，以取代液体润滑剂。最近对空调和制冷压缩机表面的初步研究表明，与最先进的聚合物涂层相比，高性能和可回收的ATSP系统表现出低摩擦系数和至少一个数量级的磨损率降低。ATSP与其他聚合物和添加剂的共混物具有为发动机、泵和压缩机提供低成本和多功能耐磨涂层的潜力。

This Small Business Innovation Research (SBIR) Phase I project aims to develop an Aromatic Thermosetting Copolyester (ATSP) system and process it into highly-effective wear resistant coatings. Surface treatments and coatings are key to improving wear performance and durability in a wide array of applications. In this project, different ATSP powder blends will be studied. Coatings of ATSP/PTFE blends on metal substrates (using sintering) will be produced. Tribological tests of these coatings under industrially-relevant conditions will be performed. Preliminary spray coatings from the ATSP powder blends will also be explored. The broader/commercial impact of this project will be the potential to provide ultra-low wear coatings for mechanical devices, such as air-conditioning and refrigeration compressors, to replace the liquid lubricants. Recent preliminary research on air-conditioning and refrigeration compressor surfaces has shown that high-performance and recyclable ATSP system exhibit low friction coefficient and at least one order of magnitude reduction in wear rate compared to the state-of-art polymeric coatings. Blends of ATSP with other polymers and additives have the potential to offer low-cost and versatile wear resistant coatings for applications in engines, pumps and compressors.
