The Innovative Reinforcement Technology of Thin Wall Ceramic Substrate Having High Coatability 2000-01-0496

By focusing on light weight and high coatability, a substrate has been successfully developed that has strong and stiff walls but does not sacrifice porosity. For increasing the isostatic strength, outermost cells of substrate are thickened more than inner cells. Furthermore, for preventing the front section of substrate from abrasion by strong deflected exhaust gas flow or contamination, only several millimeters of the front section are stiffened. This reinforced substrate is stronger and stiffer than the low porosity's one, and its coatability is as same as the current substrate.
