This Small Business Technology Transfer (STTR) Phase I project aims to develop a novel thermal spray coating process called "Hybrid Spray," for producing nano sized particulate dispersed metallic coatings. The introduction of nanoparticulates into the metal matrix is desired to improve creep strength as well as high temperature wear and oxidation resistance. This work will target the development of coatings for power generation industry where the ability to operate at higher temperatures will enable greater efficiencies and the longevity of coatings will reduce the operating costs. Midwest Thermal Spray (MTS) will develop the `Hybrid Spray' technology conceptualized at the University of Michigan. The process offers the benefits of low cost wire stock and high productivity combined with noticeably improved coating density. Current techniques for fabricating nano particle embedded engineered materials involve multiple processing steps leading to high manufacturing cost. As a result, the widespread application of nano particulate dispersed coatings in commercial applications is severely limited. The "Hybrid" spray system to be developed can be a generic system for creating and introducing nanoparticles into variety of matrix materials for different applications.

该小型企业技术转让 (STTR) 第一阶段项目旨在开发一种称为“混合喷涂”的新型热喷涂工艺，用于生产纳米级颗粒分散金属涂层。需要将纳米颗粒引入金属基体中以提高蠕变强度以及高温耐磨性和抗氧化性。这项工作的目标是开发用于发电行业的涂料，在较高温度下运行的能力将提高效率，并且涂料的使用寿命将降低运营成本。中西部热喷涂 (MTS) 将开发密歇根大学概念化的“混合喷涂”技术。该工艺具有低成本线材和高生产率以及显着提高的涂层密度的优点。当前制造纳米颗粒嵌入工程材料的技术涉及多个加工步骤，导致制造成本较高。因此，纳米颗粒分散涂层在商业应用中的广泛应用受到严重限制。待开发的“混合”喷雾系统可以是一个通用系统，用于创建纳米颗粒并将其引入各种不同应用的基质材料中。
