US-Egypt Cooperative Research: Solid Free Form Fabrication (SFF) of Self-Bonded Silicon Carbide

描述：该奖项旨在支持新泽西州皮斯卡塔韦市罗格斯大学陶瓷与材料工程系Ahmad Safari博士和埃及开罗Helwan市中央冶金研究与发展研究所Emad Ewais博士之间的合作项目。研究人员计划研究通过固体自由成形制造技术（SFF）从碳化硅粉末中制造自粘合碳化硅（SBSiC）部件。同样的材料也将由热等静压（HIP）生产，用于比较研究，以基准SFF工艺的有效性。研究人员将研究这些成形技术在复杂形状物体、近净形状、完全或接近完全致密部件制造中的应用。产品的质量将通过微观结构、物理、机械、热学和电学性能的研究来评估。这次调查的结果将被分析和报告。美国和埃及团队的研究工作将产生协同效应。适用范围：在高级陶瓷的制造中，由于在加工过程中需要严格控制所有步骤，因此难以达到所需的产品性能规格。此外，通过传统工艺制造新的陶瓷部件需要漫长而昂贵的模具设计和制造。在过去十年中，SFF技术的出现为大幅度减少原型时间和成本创造了机会。SFF也适合生产小批量的定制特色产品。该项目将检查这种特殊技术的参数，该技术能够获得成本效益，迭代设计和陶瓷部件性能控制。这项工作的结果将有利于教育美国和埃及这一领域的工程师、学生和研究人员。Safari博士是制造技术方面的专家，而Ewais博士是碳化硅方面的专家。罗格斯大学的一名博士后将参与这项研究。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

The investigators plan to study the manufacture of self-bonded Silicon Carbide (SBSiC) parts from silicon carbide powder via solid free form fabrication technique (SFF). The same material will also be produced by hot isostatic pressing (HIP) for comparative studies to benchmark the effectiveness of the SFF process. The investigators will examine the application of these forming techniques to the manufacture of complex shape objects, near-net shape, fully or near fully dense components. The quality of the products will be evaluated through studies of microstructure, physical, mechanical, thermal and electrical properties. The results of this investigation will be analyzed and reported. There will be a synergy between the research efforts of the U.S. and Egyptian teams.Scope: In the manufacturing of advanced ceramics the desired product performance specifications are difficult to achieve because of the need for strict control of all steps during processing. Also, the manufacturing of new ceramic parts by conventional processing requires lengthy and costly design and building of molds. The advent of SFF technology in the last decade has created an opportunity to drastically reduce prototyping time and cost. SFF also lends itself to manufacturing of small quantities of tailor-made specialty products. This project will examine the parameters of this special technique, which gives the ability to obtain cost effective, iterative design and control of the properties of ceramic parts. The results of this work will be of benefit in educating engineers, students and researchers in this field in the United States and in Egypt. Dr. Safari is an expert in the manufacturing technique, while Dr. Ewais is expert in SiC. A postdoctorate at Rutgers will participate in the research. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
