简介 The invention relates to a process for obtaining a hydrophobic coating on a substrate, preferably consisting of a glass material, a ceramic or a glass-ceramic, said process being characterized in that it comprises : a) a first deposition step, consisting in applying a primer first layer essentially consisting of the silicon oxycarbide SiOxCy type on said substrate, said primer layer having an RMS surface roughness of greater than 4 nm; b) an activation step, in which said SiOxCy primer layer is activated by a plasma of a gas chosen from the noble gases of the Ar or He type and the gases N2, O2 or H2O or by a plasma of a mixture of these gases; and c) a second deposition step, in which a hydrophobic coating comprising at least one fluorocompound, preferably a fluoroalkylsilane, is deposited on said first layer. The invention also relates to hydrophobic glazing comprising or formed by a substrate as defined above, this glazing being in particular used as glazing for transport vehicles or for buildings.
