Abstract:
1. An assembly used in the creation of an oven door, comprising: an inner glass substrate and an outer glass substrate of an oven door, wherein the inner glass substrate is the innermost glass substrate in the oven door; a first transparent conductive coating supported by a first major surface of the inner glass substrate, the first surface being farthest from the outer glass substrate; and a second sputter-deposited transparent conductive coating supported by a second major surface of the inner glass substrate, the second surface being closest to the outer glass substrate, wherein the second transparent conductive coating of the oven door comprises: a first barrier layer comprising silicon nitride provided on the second surface of the inner glass substrate, a first nickel chromium inclusive contact layer provided on the first barrier layer, a silver-inclusive conductive layer provided on the first contact layer, a second nickel chromium inclusive contact layer provided on the conductive layer, a second barrier layer comprising silicon nitride provided on the second contact layer, and a protective overcoat including zirconium oxide provided on the second contact layer.
