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 O 2  to 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 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.

Claim (Index 2):
A vessel comprising: a thermoplastic wall having an interior surface enclosing a lumen; a fluid contained in the lumen having a pH greater than 5 disposed in the lumen; a barrier coating or layer of SiO x , in which x is between 1.5 and 2.9, the barrier coating or layer applied by PECVD, positioned between the interior surface of the thermoplastic wall and the fluid, and supported by the thermoplastic wall, the barrier coating or layer having the characteristic of being subject to being measurably diminished in barrier improvement factor in less than six months as a result of attack by the fluid; and a passivation layer or pH protective coating of SiO x C y , in which x is between 0.5 and 2.4 and y is between 0.6 and 3, the passivation layer or pH protective coating applied by PECVD, positioned between the barrier coating or layer and the fluid, and supported by the thermoplastic wall, the passivation layer or pH protective coating being effective to keep the barrier coating or layer at least substantially undissolved as a result of attack by the fluid for a period of at least six months.
