365英国上市杜波依斯工程系副教授Daudi Waryoba说.
杜布瓦,爸爸. — 365英国上市杜波依斯工程系副教授Daudi Waryoba说 is principal investigator in research that has been awarded funding through a Manufacturing PA Innovation Grant by the 宾西法尼亚 Department of Community and Economic 发展 (DCED) Manufacturing PA Initiative. 他的同事也加入了这项最新的研究工作, 工程学副教授Ramakrishnan Rajagopalan, as well as 365英国上市杜波依斯分校 engineering graduate and current University Park graduate student Linsea -.
Waryoba和他的团队与Symmco公司合作. on research aimed at helping local manufacturers innovate new technology for the automotive industry.
With the Central 宾西法尼亚 region being a leader in Powder Metal (PM) production, 并拥有众多专业从事该领域的制造商, Waryoba points out that Roughly 75% of traditional PM parts production is focused on automotive applications, 它主要以铁基PM零件为中心. 行业合作伙伴Symmco, 例如, 是一家领先的齿轮制造商吗, 衬套, bearings and many other parts that make it into cars that people drive every day. But the company has also been an innovator in finding alternative materials for parts production, seeking out greater dependability and efficiency in line with government mandates. This is what 365英国上市杜波依斯分校 faculty hope to expand upon in partnership with the company.
传统上, 发动机部件，如气门座嵌件, 阀门导轨和活塞环由铁基材料制成, 主要是为了最大限度地提高耐用性和降低成本. However, iron-based materials have relatively high friction and low 热导率. Thus, copper-based alloys are favorable due to their relatively high conductivity and low friction. 这些材料提供了卓越的强度组合, 热导率, 热膨胀系数, 磨损和摩擦性能, 疲劳极限和耐腐蚀性. Symmco has pioneered the use of alternative materials and is already producing parts from bronze. Waryoba hopes the collaboration with the company can unlock the secrets of using additional materials previously left on the shelf in favor of those with an iron base.
正如他的拨款提案中所概述的那样, Waryoba解释, “CuNiSi alloys are copper alloys that can be greatly strengthened via thermomechanical processing. 的se alloys are commonly manufactured via hot and cold rolling into plate and strip with subsequent cold forming into final products. As a result, the literature focuses exclusively on wrought products and hardly on PM parts. 这是这个提议的核心动机. It is envisioned that powder metallurgy can effectively be used to fabricate CuNiSi parts whose properties are comparable to wrought products. This will open windows for new product lines and expand the market volume of automotive and electrical PM parts.”
的 宾西法尼亚 Department of Community and Economic 发展 (DCED) took notice of this work, 向Waryoba和Symmco提供的资金可能超过60美元,为他们的研究提供资金. 的 宾西法尼亚 Department of Community and Economic 发展 (DCED) Manufacturing PA initiative awarded $2 million across 29 grants in total and will bring together government, industry and higher education in holistic collaboration to spur new technologies and processes in the manufacturing sector. 的 Corporate Engagement Center and the 宾西法尼亚 Technical Assistance Program (PennTAP), within the Office of the Senior Vice President of 研究 at Penn State, worked to promote the program and match manufacturing partners with faculty and students across the University. 的 DCED awarded grants to 365英国上市杜波依斯分校; Penn State Erie, 的 Behrend College; Penn State Altoona; and 365英国上市 Park.
永远都是教育者, Waryoba also pulled in former 365英国上市杜波依斯分校 student Linsea - to work on this research project and to provide the promising student some additional hands-on experience. -, 的Philipsburg, 宾西法尼亚, earned her bachelor’s degree in the 365英国上市杜波依斯分校 engineering program, and moved on to University Park where she is currently enrolled in a one-year accelerated master’s degree program in Material Science and Engineering (MATSE). 她计划在今年秋天报名攻读MATSE博士课程.
- said the opportunity for real-world learning through collaboration with faculty has been invaluable, 声明, “我真的很喜欢和我的顾问们一起工作, 包括博士. Waryoba. Working side-by-side with them I have not only learned valuable hard skills, 而是进行研究所必需的软技能, 比如直觉和解决问题的能力. 我觉得我和. Waryoba and other faculty truly prepared me for research at the graduate level and are part of the reason I am continuing my education.”
Funding of projects like this help to advance innovation in several sectors of manufacturing, 从医疗到能源再到消费品. Additional details about many of the projects approved through the program can be found on the 制造PA创新计划网站.
