  • METHOD OF FORMING AN ALUMINOSILICATE-ZEOLITE LAYER ON AN ALUMINIUM-CONTAINING METALLIC SUBSTRATE AND USE OF THE SUBSTRATE OBTAINED THEREBY
    Publication number: 20180371616
    Abstract: The invention relates to a method of forming an aluminosilicate zeolite layer on an aluminium-containing metallic substrate composed of metallic aluminium or an aluminium alloy which is introduced into an alkalized aqueous reaction dispersion in which silicon and optionally aluminium are present as network-forming elements, where, irrespective of whether or not aluminium is present in the aqueous reaction dispersion, the molar ratio between the aluminium in the aqueous reaction dispersion and the sum total of the network-forming elements present in the aqueous reaction dispersion is below 0.
