多孔金属基载体材料的选择与结构设计

Structure design and material choice of porous metallic substrate supporter

载体材料是汽车尾气催化净化器的关键技术之一。根据载体的工作环境要求,提出了一种新型的多孔金属基载体材料,为增大废气与催化剂的接触面积,设计了在直通道表面具有许多微孔的多孔结构。

Substrate supporter is one of the most important components of automobile exhaust gas purifying system. A new kind of porous metallic substrate supporter is designed. In order to expand areas of catalysis and supporter,porous structure with big cells and micro-pores is designed.
