Abstract
A hard, transparent coating for a substrate and associated method for coating is disclosed. The coating includes alternating layers of a soft coating and a hard coating. The coating further includes a sensor. The electrical resistivity of the sensor may be measured to determine if the coating has been degraded. The coating may further include a hydrophobic outer layer.
Claims52
A method of forming a coating on a substrate, the method comprising:
- providing a transparent substrate;
- masking an outer perimeter strip of the substrate before depositing a coating thereon;
- then
- depositing at least one soft coating upon the substrate;
- depositing at least one hard coating upon a soft coating of the at least one soft coating;
- providing a sensor comprising an electrically conductive material;
- disposing the sensor between one soft coating of the at least one soft coating and one hard coating of the at least one hard coating;
- attaching conductive leads to the sensor;
- wherein the soft coating and the hard coating are deposited by a plasma deposition process;
- and
- wherein the soft coating and the hard coating having the general formula SiOxCy.
