IMPROVEMENTS IN THE METHOD AND APPARATUS OF VACUUM DEPOSITION.

摘要

Improvements in the method and apparatus of vacuum deposition of a highly reflective surface onto aluminum base, including unanodized roll-polished aluminum, wherein a coil of the aluminum is disposed within the vacuum chamber, both as it unwinds and as it rewinds, and the water vapor created by heating the aluminum web is made available to other vacuum deposition processing compartments within the vacuum chamber including a glow discharge chamber typically fueled by argon gas. A relatively thick layer of oxide is vacuum deposited onto an unanodized aluminum base as a substrate for the reflective surface.
