This Small Business Innovation Research (SBIR) Phase II project will demonstrate compatibility of a novel polytetrafluoroethylene (PTFE) composite coating with metal-polymer bearings currently on the market, scale up the coating deposition process, and implement pilot processing lines. Currently, there is a need for a method to improve adhesion at the PTFE/metal interface while also reducing corrosion, friction, and wear. The implementation of this technology will aid in the transition from traditional lubricants to solid lubricants in manufacturing and has significant implications for the US economy and the environment. Currently, annual lubrication-related maintenance costs are as high as $1 trillion, and consumption of petroleum-based lubricants is estimated to reach 43.78 million metric tons as of 2016. The effective implementation of this technology will reduce maintenance costs and downtime by eliminating premature bearing failure. This project will serve as a proof point for the adoption of nano-coating technologies for reducing friction and wear in mechanical systems. It will also reduce barriers to entry for these coatings in industries dominated by outdated lubrication practices. The total applicable market size for metal-polymer bearings is estimated to be $1.0 billion, and a substantial near-term revenue opportunity for the proposed technology in this sector will be the focus of this effort. This beachhead opportunity serves as an industry validation point for the proposed technology and an entry point to other industrial and manufacturing applications.The intellectual merit of this project is based on improving the adhesion and mechanical properties of PTFE liners in metal-polymer bearings using an adhesive biomimetic polymer. This technology increases the wear-life of PTFE coatings, allowing for applications from which they have historically been precluded due to high wear and delamination. During Phase I, the proof of concept was established through demonstration of strong adhesion, 40% reduction in friction, 80% reduction in wear and elimination of susceptibility to corrosion in current metal-polymer bearings. The focus of Phase II will be in tailoring the coatings for specific product applications and implementation. The proposed SBIR Phase II work will overcome the remaining technical hurdles and validate the use of this technology as both a solution for improving the adhesion between PTFE and substrates and as a replacement for current PTFE liners in metal-polymer bearings. The execution of this project will allow the realization of critical proof points needed by industrial partners and speed the adoption of this technology into product lines.

该小型企业创新研究 (SBIR) 第二阶段项目将展示新型聚四氟乙烯 (PTFE) 复合涂层与目前市场上的金属聚合物轴承的兼容性，扩大涂层沉积工艺，并实施试点加工线。目前，需要一种方法来提高 PTFE/金属界面的粘附力，同时减少腐蚀、摩擦和磨损。该技术的实施将有助于制造业从传统润滑剂向固体润滑剂的转变，并对美国经济和环境产生重大影响。目前，每年与润滑相关的维护成本高达 1 万亿美元，截至 2016 年，石油基润滑剂的消耗量预计将达到 4378 万吨。该技术的有效实施将通过消除轴承过早损坏来减少维护成本和停机时间。失败。该项目将成为采用纳米涂层技术减少机械系统摩擦和磨损的证据。它还将减少这些涂层进入以过时润滑实践为主的行业的壁垒。金属聚合物轴承的总适用市场规模估计为 10 亿美元，该领域拟议技术的大量近期收入机会将是这一努力的重点。这一滩头阵地机会可作为所提议技术的行业验证点以及其他工业和制造应用的切入点。该项目的智力价值基于使用粘合剂提高金属聚合物轴承中 PTFE 衬里的粘合性和机械性能仿生聚合物。该技术延长了 PTFE 涂层的磨损寿命，使其能够应用于历史上因高磨损和分层而被排除的应用。在第一阶段，通过展示当前金属聚合物轴承的强附着力、摩擦减少 40%、磨损减少 80% 以及消除腐蚀敏感性，建立了概念验证。第二阶段的重点是针对特定产品应用和实施定制涂层。拟议的 SBIR 第二阶段工作将克服剩余的技术障碍，并验证该技术的用途，既可以作为提高 PTFE 与基材之间粘附力的解决方案，也可以替代金属聚合物轴承中当前的 PTFE 衬里。该项目的执行将实现工业合作伙伴所需的关键证明点，并加速该技术在产品线中的采用。
