KATALYSATORELEMENT MIT UNTER ZU HILFENAHME EINES ELEKTRISCHEN BOGENS BESPRÜHTEN SUBSTRATS UND VERFAHREN ZUR HERSTELLUNG DIESES ELEMENTS

摘要

Electric arc spraying a metal onto a substrate produces an anchor layer on the substrate that serves as a surprisingly superior intermediate layer for a catalytic material deposited thereon. Spalling of catalytic material is resisted even when subjected to the harsh conditions imposed by small engines or in a close-coupled position for a larger engine.
