Abstract
An article is described including an article surface, a primer coating or layer of SiOx, SiOxCy or SiNxCy applied to the article surface, and a deposit of lubricant applied to the primer coating or layer. The primer coating or layer of SiOx, SiOxCy or SiNxCy is applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. A first deposit of lubricant is applied to the primer coating or layer. The primer coating or layer improves the adhesion or wetting of the lubricant on the surface to be lubricated. 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.
