Claim:
1. A syringe barrel comprising: a wall having a generally cylindrical interior surface defining an inner sliding surface and a lumen; a plasma enhanced chemical vapor deposition (PECVD) primer coating or layer on the wall defining a PECVD treated surface, in which the primer coating or layer consists essentially of SiO a deposit of fluid lubricant on the PECVD treated surface wherein the fluid lubricant comprises polydimethylsiloxane; in which the deposit of fluid lubricant and primer coating or layer is effective to provide a lower frictional resistance between the inner sliding surface and a relatively sliding part than the deposit of fluid lubricant without the primer coating or layer at least one year after the syringe barrel is assembled with a plunger.
