Abstract: A scratch-resistant glass substrate is prepared by forming a hard, scratch-resistant layer over a major surface of the substrate. The layer is formed from an inorganic material such as a metal oxide, metal nitride, metal carbide, or metal boride using, for example, physical vapor deposition such as reactive or non-reactive sputtering at a process temperature of less than 500° C. The inorganic layer is resistant to micro-ductile scratching, which can safeguard the visible appearance of the glass substrate in use. The glass substrate can include chemically-strengthened glass.
