A substrate is coated with a hydrophobic coating that includes highly tetrahedral amorphous carbon that is a form of diamond-like carbon (DLC). In certain embodiments, the coating is deposited on the substrate in a manner to increase its hydrophobicity (e.g. so that the coating has an initial contact angle .theta. of at least about 100 degrees; and/or a surface energy of no more than about 20.2 mN/m). In certain embodiments, the coating is deposited in a manner such that it has an average hardness of at least about GPa, more preferably from about 20-80 GPa.
Un substrat est revêtu d'un revêtement hydrophobe comprenant un carbone amorphe sensiblement tétraédrique, qui est une forme de carbone sous forme de diamant amorphe (CDA). Dans certaines formes de réalisation, le revêtement est déposé sur le substrat de manière à accroître les propriétés hydrophobes de celui-ci (p. ex. afin que le revêtement présente un angle de contact initial theta d'au moins environ 100 degrés; et/ou une énergie superficielle ne dépassant pas environ 20,2 mN/m). Dans certaines formes de réalisation, le revêtement est déposé de manière à présenter une dureté moyenne d'au moins environ 10 GPa, et de préférence d'au moins environ 20-80 GPa.
