Abstract
The disclosure is directed to enhanced silver coated aluminum substrates for use as optical mirrors in which galvanic corrosion between the silver and aluminum is prevented and a method of making such silver coating and mirrors. The optical mirror according to the disclosure has an in-situ formed 'barrier' layer inserted between the aluminum substrate and the silver layer. In addition, selected layers are densified by carrying out their deposition using a high power RF ion source during their deposition.
