摘要

A sputter-coated layer system including a non-nitrided and non-oxidized nickel or nickel alloy layer located between two layers of Si3N4 of the requisite thicknesses and used for architectural and automotive glass substrates so as to be heat treatable and have DELTA E characteristics sufficiently low to render the products matchable as between heat treated and non-heat treated products having the same coating thereon.
