SBIR Phase I: Novel Cermet Heating Materials for Thermal Control and Energy Efficiency

这个小型企业创新研究第一阶段项目将优化一种新开发的陶瓷-金属(Cermet)电阻加热材料，并证明其用于柴油微粒过滤器的可行性。目标包括优化金属陶瓷成分和层压板，物理性能的表征，以及开发多层陶瓷带制造方法，以生产带有集成金属陶瓷加热元件的多通道过滤器整体。这项研究将基于对寿命和温度循环、热传递能力和热梯度控制的分析来优化金属陶瓷的成分。该项目的预期结果将是一种带有集成金属陶瓷加热元件的小型颗粒过滤器，可为颗粒提供持续的热氧化。新型金属陶瓷加热材料具有直接的商业潜力，可以作为加热元件集成到柴油颗粒过滤器结构中，用于颗粒(约600摄氏度)的持续热氧化。随着新的排放控制计划于2007年生效，目前迫切需要一种紧凑、易于维护、耐用和有效的柴油微粒过滤器，适用于新的和现有的柴油动力车辆。

This Small Business Innovation Research Phase I Project will optimize a newly developed ceramic-metallic (cermet) resistive heating material and prove its feasibility for use in diesel particulate filters. Objectives include optimization of the cermet composition and laminates, characterization of physical properties, and development of multi-layer ceramic tape manufacturing methods for producing multichannel filter monoliths with integral cermet heating elements. The research will optimize the cermet composition based on analysis of life and temperature cycling, heat transfer capabilities, and thermal gradient control. The anticipated result of the project will be a small-scale particulate filter with an integral cermet heating element that provides continuous thermal oxidation of particulates. The new cermet heating material has immediate commercial potential as a heating element that can be integrated into diesel particulate filter structures for the continuous thermal oxidation of particulates (at approximately 600 C). With new emissions controls scheduled to take effect in 2007, there is presently a compelling need for a compact, simple-to-maintain, durable, and effective diesel particulate filter for both new and existing diesel-powered vehicles.
