Advanced DLC coating technique on silicone-based tubular medical devices

摘要

An advanced DLC coating technique has been developed to fabricate adhesive DLC layer on silicone-based tubular medical devices. The novelty of the multi-electrode coaxial magnetron plasma system includes the capability to produce a uniform and flexible DLC coating layer of high hardness and low friction coefficient by a chemical vapor deposition (CVD)-physical vapor deposition (PVD) hybrid technique. In addition, it is a simple single-step process such that pretreatment is not required on the silicone-based substrate.
