该小型企业创新研究第一阶段项目将优化新开发的陶瓷-金属（金属陶瓷）电阻加热材料，并证明其用于柴油机颗粒过滤器的可行性。目标包括优化的金属陶瓷组合物和层压板，物理性能的表征，和多层陶瓷带制造方法的发展，用于生产多通道过滤器整体与整体金属陶瓷加热元件。该研究将根据寿命和温度循环、传热能力和热梯度控制的分析来优化金属陶瓷成分。该项目的预期成果将是一个小型颗粒过滤器，带有一个整体金属陶瓷加热元件，可对颗粒进行连续的热氧化。这种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机颗粒过滤器结构中，用于颗粒的连续热氧化（约600 ℃）。随着新的排放控制计划于2007年生效，目前迫切需要一种用于新的和现有的柴油动力车辆的紧凑、易于维护、耐用和有效的柴油颗粒过滤器。

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.
