Comparing with the ceramic substrate, metallic substrate has the advantages of fast burning, small volume, high mechanical strength, prominent heat-resistance, etc. It is widely used in exhaust gas purification equipments, such as motorbike, yacht etc.
The metallic substrate should be pretreated to generate a transition layer which is to solve the mismatched heat expansion between metallic substrate itself and the active layer. On the transition layer, it is coated with the rare earth catalyst layer, while in active layer is coated with noble metal like Pt,Pd,Rh
