Title:
ALUMINIUM-TITANIUM ALLOY WITH HIGH SPECULAR REFLECTIVITY, REFLECTING COATINGS COMPRISING SAME AND MIRRORS AND PARTS COMPRISING SAID COATING
Document Type and Number:
WIPO Patent Application WO2001006026
Kind Code:
A3
Abstract:
The invention concerns a metal alloy based on aluminium and titanium whereof the aluminium content ranges between 80 and 90 atoms per hundred and the titanium content ranges between 10 and 20 atoms per hundred. The invention is characterised in that it is microcrystalline and outside thermodynamic equilibrium, said alloy being thereby resistant to oxidation and corrosion and having at the same time remarkable adhesion to polymer materials. The invention also concerns a reflecting coating of said metal alloy, preferably of thickness ranging between 0.01 and 3 mu m, covered with a protective film, preferably in polymer material. The invention further concerns a special mirror having specular reflectivity not less than about 65 %, good resistance to corrosion and oxidation comprising a substrate, preferably in polymer material supporting the inventive reflecting coating. The invention finally concerns parts comprising such a mirror, such as motor vehicle rear-view mirrors.
