Abstract

A coated article includes a glass substrate supporting a coating. The coating may include, moving away from the glass substrate, a layer comprising diamond-like carbon (DLC); a layer comprising zinc oxide, wherein a concentration of OH-groups at a surface of the layer comprising zinc oxide farthest from the glass substrate is no greater than about 40%; and a layer comprising aluminum nitride on the glass substrate over and directly contacting the layer comprising zinc oxide. The DLC layer may be temporary, and designed to be burned off during heat treatment.
