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

本研究的目的是开发一种实验-理论多尺度的方法，其关键是通过电泳沉积的常温组装和通过烧结的高温固结的优化集成，从而通过协同的网络形状使能工艺序列来生产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细观水平上定制材料结构，从而可以生产具有所需功能梯度结构的网状颗粒材料，在连续烧结后呈现所需的最终形状和所需的细观结构。所开发的方法将为制造具有增强性能的广泛的功能结构粉末组件系统提供基础，例如生物植入物、电子电路、MEMS组件、传感器等。该计划的合作内容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加工的当地行业的合作。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.
