ABSTRACT:
A corrosion-resistant low-emissivity coating is provided. The low-emissivity coating comprises, in sequence outwardly, a corrosion-resistant inner infrared-reflective layer, a transparent dielectric middle coat, and an outer infrared-reflective layer. The outer infrared-reflective layer consists essentially of silver and the corrosion-resistant inner infrared-reflective layer has a different composition than the outer infrared-reflective layer. Also provided are methods for depositing coatings of this nature, as well as substrates bearing these coatings.
