TSE Temperature Micromolding Aluminum Parts

项目摘要

This award is made under the NSF/EPA Partnership for Environmental Research TSE 2001. The research objective of this effort is to demonstrate the technical feasibility of mass replication of high-aspect-ratio metallic miroparts by fabricating aluminum cross-flow heat exchanges. Currently a major technical barrier to mass replication of aluminum parts by high temperature micromolding is the undesirable interaction between the hot/molten aluminum and micromold. This leads to soldering and consequently the inability to separate the mold from the molded aluminum part. The approach to be taken is to uniformly coat highly nonplanar micromolds in a manner that it makes it possible to eject the aluminum part from the miromold after molding operation. This will be achieved by using plasma-assisted, vapor-phase deposition technology to deposit conformal coatings with uniform chemical and mechanical properties onto the surfaces of high-aspect-ratio micromolds. Mircomolds are fabricated using the deep X-ray lithography/electrodeposition based microfabrication technique at the Center for Advanced Microstructures and Devices at Louisiana State University.If successful, this research will allow modification of the near-surface properties of the micromold to enable easy and repeated mold/part separation, hence removing a major existing technical barrier in mass replication of aluminum parts by high temperature micromolding. This will lead to increased end-use energy savings and efficiencies associated with the creation of compact heat exchangers.

该奖项是在 NSF/EPA 环境研究 TSE 2001 合作伙伴关系下颁发的。这项工作的研究目标是证明通过制造铝横流换热器大规模复制高纵横比金属微型零件的技术可行性。目前，通过高温微成型大规模复制铝部件的主要技术障碍是热/熔融铝与微模具之间的不良相互作用。这会导致焊接，从而导致无法将模具与模制铝部件分离。所采取的方法是均匀地涂覆高度非平面的微模具，使得可以在模制操作之后将铝部件从微模具中弹出。这将通过使用等离子体辅助气相沉积技术将具有均匀化学和机械性能的保形涂层沉积到高纵横比微模具的表面来实现。微型模具是在路易斯安那州立大学先进微结构和器件中心使用基于深 X 射线光刻/电沉积的微加工技术制造的。如果成功，这项研究将允许修改微模具的近表面特性，从而实现轻松、重复的模具/零件分离，从而消除通过高温微成型大规模复制铝零件的现有主要技术障碍。这将导致最终使用的能源节约和与紧凑型热交换器的创建相关的效率的提高。
