1. A syringe or syringe parts comprising:
- a barrel and a piston, the barrel having an inner surface and the piston having a side surface engaging the barrel inner surface, wherein at least one of the inner surface and the side surface is a substrate coated with a lubricity layer configured to provide a lower piston sliding force or breakout force than the uncoated substratethe lubricity layer having one of the following atomic ratios, measured by X-ray photoelectron spectroscopy (XPS), SiwOxCy or SiwNxCy, where w is 1, x in this formula is from about 0.5 to 2.4, and y is from about 0.6 to about 3;
the lubricity layer having a thickness by transmission electron microscopy (TEM) between 10 and 500 nm;
the lubricity layer deposited by plasma enhanced chemical vapor deposition (PECVD) under conditions effective to form a coating from a precursor selected from a linear siloxane, a monocyclic siloxane, a polycyclic siloxane, a polysilsesquioxane, a linear silazane, a monocyclic silazane, a polycyclic silazane, a polysilsesquiazane, a silatrane, a silquasilatrane, a silproatrane, an azasilatrane, an azasilquasiatrane, an azasilproatrane, or a combination of any two or more of these precursors.

Abstract
Methods for processing a vessel, for example to provide a gas barrier or lubricity, are disclosed. First and second PECVD or other vessel processing stations or devices and a vessel holder comprising a vessel port are provided. An opening of the vessel can be seated on the vessel port. The interior surface of the seated vessel can be processed via the vessel port by the first and second processing stations or devices. Vessel barrier, lubricity and hydrophobic coatings and coated vessels, for example syringes and medical sample collection tubes are disclosed. A vessel processing system and vessel inspection apparatus and methods are also disclosed.
