METHOD OF PREPARING HIGH DENSITY METAL OXIDE LAYERS AND THE LAYERS PRODUCED THEREBY

摘要

A method for the production of an oxide layer, involving oxidizing a metal surface, wherein the metal surface is electrically connected to an electronic control unit (ECU); wherein the metal oxide layer produced has an amount of metal present in said metal oxide layer that is higher than that present in a metal oxide layer produced by oxidizing the metal surface in the absence of the ECU; or oxidizing an oxidizable non-metallic conductive surface, wherein the oxidizable non- metallic conductive surface is electrically connected to an electronic control unit (ECU); wherein the oxide layer produced is denser than that produced by oxidizing the oxidizable non-metallic conductive surface in the absence of the ECU; and the metal oxide or oxide layers produced thereby.
