Titanium nickel niobium alloy barrier for low-emissivity coatings

摘要

A method for making low emissivity panels, including control the composition of a barrier layer formed on a thin conductive silver layer. The barrier structure can include a ternary alloy of nickel, titanium, and niobium, which showed improvements in overall performance than those from binary barrier results. The percentage of nickel can be between 5 and 15 wt %. The percentage of titanium can be between 30 and 50 wt %. The percentage of niobium can be between 40 and 60 wt %.

1. A method of forming a low emissivity panel, the method comprising:
providing a transparent substrate; forming a first layer above the transparent substrate, wherein the first layer comprising silver; and forming a second layer above the first layer, wherein the second layer comprises an alloy of nickel, titanium, and niobium, wherein the percentage of nickel in the alloy is about 10 wt %, the percentage of titanium in the alloy is about 40 wt %, and the percentage of niobium in the alloy is about 50 wt %.
