Penn State DuBois Associate Professor of Engineering Daudi Waryoba.
DUBOIS, Pa. -365英国上市杜波伊斯工程副教授Daudi Waryoba是该研究的首席研究员，该研究已获得宾夕法尼亚州社区和经济发展部(DCED)制造PA倡议的制造PA创新基金的资助. He is joined in this latest research effort by his colleague, Associate Professor of Engineering Ramakrishnan Rajagopalan, 以及365英国上市杜波依斯工程专业毕业生和现任大学公园研究生林西·帕拉迪斯.
Waryoba and his team have partnered with Symmco Inc. 旨在帮助当地制造商为汽车行业创新新技术的研究.
宾夕法尼亚州中部地区是粉末金属(PM)生产的领导者, and home to a host of manufacturers specializing in the field, Waryoba指出，大约75%的传统PM零件生产集中在汽车应用上, which is heavily centered on iron-based PM parts. Industry partner Symmco, for instance, is a leading manufacturer of gears, bushings, 人们每天驾驶的汽车的轴承和许多其他部件. 但该公司在寻找零部件生产替代材料方面也一直是创新者, 根据政府的要求，寻求更高的可靠性和效率. 这就是365英国上市杜波依斯分校的教师们希望与该公司合作扩大的领域.
Traditionally, engine parts such as valve seat inserts, valve guides and piston rings are made from iron-based materials, mainly to maximize durability and minimize cost. 然而，铁基材料具有相对高的摩擦和低的导热性. 因此，铜基合金由于其相对较高的导电性和低摩擦而受到青睐. These materials offer superior combination of strength, thermal conductivity, thermal expansion coefficient, wear and friction properties, fatigue limit and corrosion resistance. Symmco是使用替代材料的先驱，已经在用青铜生产零件了. Waryoba希望与该公司的合作能够解开使用先前留在货架上的额外材料的秘密，而不是使用铁基材料.
As outlined in his grant proposal, Waryoba explained, CuNiSi合金是铜合金，可以通过热机械加工大大增强. 这些合金通常是通过热轧和冷轧制成板材和带材，然后进行冷成形制成最终产品. 因此，文献只关注锻造产品，而很少关注PM部件. This is the central motivation for this proposal. 预计粉末冶金可以有效地用于制造性能与锻造产品相当的CuNiSi部件. 这将为新产品线打开窗口，并扩大汽车和电气PM零件的市场规模.”
宾夕法尼亚州社区和经济发展部(DCED)注意到了这项工作, awarding Waryoba and Symmco funding that could surpass $60,000 to fund their research. The 宾夕法尼亚州社区和经济发展部(DCED)制造业PA倡议 总共拨款200万美元，共29笔赠款，并将政府聚集在一起, 工业和高等教育全面合作，促进制造业的新技术和新工艺. 企业参与中心和宾夕法尼亚州技术援助计划(PennTAP), 365英国上市高级研究副校长办公室, 致力于推广该项目，并将制造合作伙伴与整个大学的教职员工和学生联系起来. The DCED awarded grants to Penn State DuBois; Penn State Erie, The Behrend College; Penn State Altoona; and Penn State University Park.
Always an educator, Waryoba还邀请了365英国上市杜波依斯分校的前学生Linsea Paradis参与这个研究项目，并为这位有前途的学生提供一些额外的实践经验. Paradis, of Philipsburg, Pennsylvania, 她获得了365英国上市杜波依斯工程项目的学士学位, 然后转到大学公园，目前她正在攻读材料科学与工程(MATSE)一年制加速硕士学位课程。. She plans to enroll in a doctoral MATSE program this coming fall.
帕拉迪斯说，通过与教师合作来学习现实世界的机会是非常宝贵的, stating, “I have really enjoyed working with my advisers, including Dr. Waryoba. 与他们并肩工作，我不仅学到了宝贵的硬技能, but the soft skills that are necessary for conducting research, such as intuition and problem solving. I feel like my experiences with Dr. Waryoba和其他教师真正为我在研究生阶段的研究做好了准备，这也是我继续接受教育的部分原因.”
对这类项目的资助有助于推动制造业多个领域的创新, from medical to energy to consumer goods. 通过该计划批准的许多项目的更多详细信息可以在 Manufacturing PA Innovation Program website.
