METHOD FOR PRODUCING A METAL-OXIDE-COATED WORKPIECE SURFACE WITH PREDETERMINABLE HYDROPHOBIC BEHAVIOUR

It is proposed to produce a workpiece (10) with a metal-oxide-coated surface (9) with a selectable degree of hydrophobic behaviour, by the surface of a substrate material (1) being provided at least in partial regions with a microstructure (2, 3) by mechanical embossing and subsequently being coated...

Zusammenfassung:	It is proposed to produce a workpiece (10) with a metal-oxide-coated surface (9) with a selectable degree of hydrophobic behaviour, by the surface of a substrate material (1) being provided at least in partial regions with a microstructure (2, 3) by mechanical embossing and subsequently being coated. The microstructuring is followed by depositing a hydrocarbon- or silicon-dioxide-containing protective layer (6) and/or at least one top layer (7), on the surface (9) of which the desired hydrophobic properties occur. The sterilizing and catalytic effect of the metal-oxide-containing top layer (7) is enhanced or produced by incorporation of metal-containing nanoparticles.
