Method of making coated article including layer(s) of diamond-like carbon which may be hydrophobic
First Claim
1. A method of making a coated article, the method comprising:
- providing a substrate;
depositing a first DLC inclusive layer on the substrate using a first gas including silicon (Si); and
depositing a second DLC inclusive layer on the substrate and on the first DLC inclusive layer using a second gas different than the first gas so that the resulting article has an initial contact angle θ
of at least about 80 degrees.

Abstract
A process includes coating a substrate with a hydrophobic coating system including highly tetrahedral amorphous carbon that is a form of diamond-like carbon (DLC). In certain embodiments, the coating system is deposited on the substrate in a manner to increase its hydrophobicity. In certain embodiments, the coating system is deposited in a manner such that it has an average hardness of at least about 10 GPa, more preferably from about 20-80 GPa. In certain embodiments, the coating system includes first and second DLC inclusive layers that are deposited using one or more ion beam deposition devices, wherein different gases are used to deposit the respective DLC inclusive layers such that the overlying layer has greater scratch resistance characteristics than the underlying layer which functions as an anchoring layer.
