| Abstract: | Automobile exhaust gas purifying system in which metallic substrate is used is impendent for thestrict limitation of the automobile exhaust pollution,but there are lots of difficulties to be settled. In this text,the de-velopment of materials for substrates is stated, the advantages and defects are compared between metallic substratesand ceramic substrates,and the metallic substrates are specially introduced. Had metallic substrates been sued,the pu-rifying efficiency of purifying system will be elevated greatly and the life-time will be elongated. But the processingand shaping technology is so complex, and the properties of substrate materials, common Fe-Cr-Al alloys, should beimproved. |
