SBIR Phase II: Ultrananocrystalline Diamond as Wear Resistant and Protective Coating for Mechanical Shaft Seal Applications

该小型企业创新研究(SBIR)二期项目将基于一种名为超纳米晶(Tm)金刚石(UNCDtm)的新型材料的优点，开发一种新型机械轴封，这种密封将导致与工业抽水和涡轮机械应用相关的更长寿命、节能和减少环境排放的密封。机械轴封几乎应用于所有行业。这些密封件的主要功能是确保泵送的流体不会从系统中逸出，并保护流体免受污染。该计划将建立在早期结果的基础上，这些结果表明，UNCD可以比碳化硅密封件减少密封件磨损数量级。该项目将包括客户试验、获得行业标准资格和开发制造能力。将为化工、炼油、制药、采矿和其他要求苛刻的工业应用开发新的UNCD密封产品。UNCD的几个特点，包括其细小的颗粒尺寸、高质量的表面和在合理温度下进行加工的能力，使其成为利用其他摩擦和磨损材料的理想材料。

This Small Business Innovation Research (SBIR) Phase II project will develop a new class of mechanical shaft seals based on the benefits of a novel material called Ultrananocrystalline (tm) diamond (UNCDtm) that will result in seals that last longer, save energy and reduce environmental emissions associated with industrial pumping and turbo-machinery applications. Mechanical shaft seals are used in almost every industry. The main functions of these seals are to ensure that the pumping fluid does not escape the system and to protect the fluids from contaminants. This program will build upon earlier results that showed that UNCD could reduce seal wear by orders of magnitude over SiC seals. The project will include customer trials, securing industry standard qualification and developing manufacturing capabilities. New UNCD seal products will be developed for chemical, refinery, pharmaceutical, mining, and other demanding industrial applications. Several features of UNCD, including its fine grain size, high quality surface and its ability to be processed at reasonable temperatures, make it an ideal material to be leveraged other friction and wearmaterials.
