Direktes Aufbringen von Katalysatoren auf die Oberflächen von Wärmetauschern von Fahrzeugen durch thermische Spritzverfahren zur Reinigung der Atmosphere

摘要

Formation of a catalytically-active surface on a substrate, for treatment of atmospheric pollution, involves applying the molten catalytic metal from the thermal spray system directly onto a substrate material surface, the molten catalytic metal forming a direct bond to the substrate and forming a catalytically-active layer on the substrate material surface. Formation of a catalytically-active surface on a substrate, for treatment of atmospheric pollution, involves providing a feedstock of at least one catalytic metal to a thermal spray system, the thermal spray system forming a molten catalytic metal; and applying the molten catalytic metal from the thermal spray system directly onto a substrate material surface, the molten catalytic metal forming a direct bond to the substrate and forming a catalytically-active layer on the substrate material surface. The catalytically-active layer is capable of catalyzing the conversion of at least one of ozone, hydrocarbons, or carbon monoxide to oxygen, water, and carbon dioxide, respectively. The surface and the substrate material are free from binders of the molten catalytic metal.
