Abstract:
A coated glass article comprising:a glass substrate comprising, on a weight basis: SiO2 from about 60-80%, Na2O from about 10-20%, CaO from about 0-16%, K2O from about 0-10%, MgO from about 0-10%, Al2O3 from about 0-5%; a hydrophobic coating system including diamond-like carbon (DLC) and sp3 carbon-carbon bonds provided on said glass substrate; said hydrophobic coating system including first and second DLC inclusive layers, said first layer including silicon (Si) and being provided between said second layer and said substrate; wherein said second layer is deposited in a manner so that said second layer has a higher hardness and higher density than said first layer; and wherein said hydrophobic coating system has an initial contact angle &thgr; with a sessile drop of water thereon of at least about 80 degrees, and an average hardness of at least about 10 GPa.
