Abstract

A method for enhancing metal corrosion resistance of a metal deposited on a substrate is provided. The method includes contacting the metal coated substrate with a treating composition including metal oxide nano-particles. Furthermore, a method for making a mirror comprising a substrate having a metal coated thereon is provided, wherein the method includes contacting the metal coated substrate with a treating composition including metal oxide nano-particles. Preferably, the metal oxide nano-particles are selected from one or more oxides of zinc, iridium, tin, aluminum, cerium, chromium, vanadium, titanium, iron, indium, copper, gold, palladium, platinum, manganese, cobalt, nickel, zirconium, molybdenum, rhodium, silver, indium, wolfram, iridium, lead, bismuth, samarium, erbium, or mixtures of these materials. In addition, products obtainable by these methods are provided.
