Abstract
A method for providing a passivation layer or pH protective coating on a substrate surface by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising polymerizing gases. The lubricity, passivation, pH protective, hydrophobicity, and/or barrier properties of the passivation layer or pH protective coating are set by setting the ratio of the Oto the organosilicon precursor in the precursor feed, and/or by setting the electric power used for generating the plasma. In particular, a passivation layer or pH protective coating made by the method is provided. Pharmaceutical packages coated by the method and the use of such packages protecting a composition contained in the vessel against mechanical and/or chemical effects of the surface of the package without a passivation layer or pH protective coating material are also provided.
