Process for forming a reflective surface

摘要: A process for forming a reflective surface, comprises the steps of: providing at least part of one unanodized surface which has peak-to-valley height Ra equal to or less than 1 micron. The is selected from group consisting (1) refined aluminum with degree purity greater 98.3% by weight and (2) alloys element Si, Mg, Mn, Cu, Zn, Fe. in form rolled foil, sheets, strips said used as substrate. further includes depositing two layers gas phase on wherein include ceramic adhesive layer reflecting reflection radiation wavelengths optical range. aluminum, silver, gold, copper containing gold copper.
