SBIR Phase I: A New Method for Deposition of Powder Materials

这个小企业创新研究（SBIR）第一阶段项目的重点是开发一种具有成本效益和可扩展的粉末金属沉积方法。该方法的独特性源于精确定制的表面制备与热喷涂工艺相协调，其目标是在涂层材料和基体之间实现完全熔融的冶金结合。与传统方法相比，改进的粘合将有利于涂层应用，从高温应用的热保护，恶劣环境的耐腐蚀性以及增强表面机械性能（如韧性和硬度）。研究工作的目的是在原型环境中证明该概念的可行性，这将通过实验和计算工作来完成。除了证明概念之外，第一阶段研究的一个重要方面将是更深入地了解有影响的处理变量，以及概念的能力和局限性，以便为第二阶段倡议设计一个放大的设备。

This Small Business Innovation Research (SBIR) Phase I Project focuses on the development of a cost effective and scaleable approach to powder metal deposition. The uniqueness of the approach stems from a precisely tailored surface preparation coordinated with a thermal spray process with a goal of achieving a fully fused, metallurgical bond between the coated material and the substrate. Improved bonding as compared with conventional approaches would benefit coating applications ranging from thermal protection for high temperature applications, corrosion resistance for harsh environments and enhancement of surface mechanical properties such as toughness and hardness. The research effort is aimed at proving the feasibility of the concept in a prototype environment, which will be accomplished with both experimental and computational efforts. In addition to proving the concept, an important aspect of the Phase I research will be to gain a stronger understanding of the influential processing variables, as well as concept capabilities and limitations, in order to design a scaled up device for a Phase II initiative.
