Net-Shape Manufacturing of Powder Components by Electrophoretic Deposition and Sintering

本研究的目的是开发一种实验-理论的多尺度方法，其关键方面是通过电泳沉积和烧结高温固结来优化环境温度组装的集成，从而通过协同的网络形状使技术序列产生功能结构的粉末材料。所提出的方法假设通过电泳沉积在宏观和中观尺度水平上裁剪材料结构，从而允许生产具有所需功能梯度结构的净形状颗粒材料，在连续烧结后呈现所需的最终形状和所需的中观结构。所开发的方法应该为制造广泛的功能性结构粉末组件系统提供基础，如生物植入物、电子电路、MEMS组件、传感器等，具有增强的性能。该项目的合作组成部分包括与桑迪亚国家实验室的互动，与法国国家工程学院的国际合作，以及与积极参与粉末材料部件建模和变形处理的当地工业的合作。该计划将有助于材料和制造科学的进步。

The objective of this research is to develop an experimental-theoretical multi-scale approach whose key aspect is the optimized integration of the ambient temperature assembly by electrophoretic deposition and the high temperature consolidation by sintering such that functionally structured powder materials are produced by a synergistic net-shape-enabling technological sequence. The proposed approach assumes tailoring of the material structure at both macro and meso-scale levels by electrophoretic deposition which allows the production of net-shape particulate materials with required functionally graded structures, rendering the wanted final shape and the desired meso-structure after consecutive sintering.The developed methodology should provide a basis for the fabrication of a wide range of functionally structured powder component systems such as bio-implants, electronic circuits, MEMS components, sensors, etc. with enhanced properties. The collaborative component of the program includes interactions with Sandia National Laboratories, the international collaboration with National School of Engineering, France, and collaboration with local industries that have been actively involved in the modeling and deformation processing of powder material components. The program will contribute to the advancement of the Materials and Manufacturing Sciences.
