NOVELTY - The corrosion resistant mirror comprises a glass substrate, a silver coating layer (B) having a thickness e(Ag) deposited on a side of the substrate by non-electrolytic metallization and projecting an aerosol containing silver in the form of cations (oxidant) and a reducer on the side of the substrate to transform the silver cations, a protection layer (C) based on a metal other than silver deposited on the silver coating, and a finish layer (D) applied on the protection layer. The thickness e(Ag) comprises 50-120 nm. The protection layer is obtained by non-electrolytic metallization.    USE - The high corrosion resistant mirror is useful for recovery of solar energy (claimed), and as interior mirrors in bathrooms and rear-view mirror in automotive industry.    ADVANTAGE - The mirror has good reflectivity of greater than 90% thus providing optimum performance and energy recovery, and high corrosion resistance thus can be subjected to aggressive climatic and environmental conditions including sand, water, heat and UV radiation, and can be easily and economically fabricated using a non-electrolytic metallization process.    DETAILED DESCRIPTION - The corrosion resistant mirror comprises a glass substrate, a silver coating layer (B) having a thickness e(Ag) deposited on a side of the substrate by non-electrolytic metallization and projecting an aerosol containing silver in the form of cations (oxidant) and a reducer on the side of the substrate to transform the silver cations, a protection layer (C) based on a metal other than silver deposited on the silver coating, and a finish layer (D) applied on the protection layer. The thickness e(Ag) comprises 50-120 nm. The protection layer is obtained by non-electrolytic metallization of the silver coating, and has a thickness e(M) of 0.3e(Ag) less than or equal to e(M) less than or equal to 5e(Ag). The metals or alloys of two successive or continuous layers are different. An INDEPENDENT CLAIM is included for a non-electrolytic process for fabricating a mirror resistant to corrosion.
