STTR Phase II: A New Process for Boride Coatings for Manufacturing Applications

这一小型企业技术转让(STTR)第二阶段项目正在寻求一种用于渗硼涂层的新型低温金属-有机化学气相沉积(LT-MOCVD)技术的转让、进一步开发和商业化。该项目将致力于开发涂层，以表征附着力、微观结构、形态、成分和硬度。选定的涂层将在实验室测试条件下在各种常见工程基材上进行摩擦磨损和耐腐蚀性测试。前驱体的制备过程将被放大，并将在工业规模的沉积系统中进行沉积。涂层工艺将进行优化，以获得高硬度和良好的附着力。优化后的涂层将应用于最终用户的设施在生产条件下进行测试的部件。耐磨和耐腐蚀涂层的更广泛的冲击/商业潜力因其高硬度和良好的化学稳定性而非常有吸引力，并在美国制造业的许多应用中具有潜力。在该项目中开发的沉积硼化物的工艺将实现广泛的应用，包括切割工具、压铸模具和镶件、平板玻璃的转印辊、化工过程中的零部件、军工、汽车和航空航天工业。

This Small Business Technology Transfer (STTR) Phase II project is seeking the transfer and further development and commercialization of a new low temperature metal-organic chemical vapor deposition (LT-MOCVD) technology for boride coatings. The project will work to develop coatings for characterizations of adhesion, microstructure, morphology, composition and hardness. Selected coatings will be tested for friction and wear and corrosion resistance under laboratory test conditions on various common engineering substrate materials. The precursor preparation process will be scaled up and deposition will be done in an industrial scale deposition system. The coating process will be optimized for high hardness and good adhesion. Optimized coatings will be applied to components for testing at end users' facilities under production conditions.The broader impact/commercial potential of wear and corrosion resistant coatings are very attractive for their high hardness and good chemical stability, and have potential for many applications in the manufacturing sector in United States. The process developed in this project, of deposition of borides, will enable a wide spectrum of applications including cutting tools, die casting dies and inserts, transfer rolls for flat glass, components for chemical processes, armament industries, automotive and aerospace industries.
