Gas filtering structure e.g. silicon carbide filtering structure, selecting method for e.g. diesel engine, involves processing image comprising morphological erosion produced by structuring element to obtain another image

摘要

The method involves processing, according to a wall surface image, an image comprising a morphological erosion produced by a structuring element e.g. disk, in such a way that another image characterizing the uniformity and the homogeneity of a wall microstructure is obtained. Dimensions and the morphology of the structuring element are selected based on median diameter of pores, measured by mercury porosimetry. An independent claim is also included for a silicon carbide based filtering structure.
