A substrate (1) is coated with a layer(s) or coating(s) (3) that includes, for example, amorphous carbon in a form of diamond-like carbon (DLC). The DLC is then ion beam treated and/or treated with a hot liquid and/or vapor (such as hot water) so as to cause the contact angle 0 thereof to decrease. In certain example embodiments, at least oxygen gas is used in an ion beam source(s) that generates the ion beam(s) used for the ion beam treatment.

Un substrat est revêtu à l'aide d'une ou de plusieurs couche(s) ou enduit(s) comprenant, par exemple, du carbone amorphe tel que du carbone sous forme de diamant amorphe (CDA). Le CDA est ensuite traité par faisceau ionique et/ou à l'aide d'un liquide chaud et/ou de vapeur (p. ex. eau chaude) afin de réduire l'angle de contact .theta.. Dans certaines formes de réalisation, au moins de l'oxygène gazeux est utilisé dans une ou plusieurs source(s) de faisceau(x) ionique(s) produisant le(s) faisceau(x) ioniques pour le traitement par faisceau ionique.
