An article is described including an article surface, a primer coating of SiOx, SiOxCy or SiNxCy applied to the article surface, and optionally a deposit of lubricant applied to the primer coating or layer. The primer coating of SiOx, SiOxCy or SiNxCy is applied by PECVD of an organosiloxane precursor. A deposit of lubricant is applied to the primer coating or layer. The primer coating improves the adhesion or wetting of the lubricant on the surface to be lubricated, as well as the recovery of the liquid contained in the vessel. Examples of such an article are a prefilled syringe having a barrel with a lubricated interior portion and a plunger tip that slides along it. Another example of such an article is a vial having a lubricated opening to receive a septum. Another aspect of the invention is a method of making such an article.
