Method for forming diamond-like carbon film

摘要

Provided is a method for forming a diamond-like carbon (DLC) film capable of enhancing the adhesion strength of a diamond-like carbon (DLC) film by simple steps. A surface of a substrate 11 made of polytetrafluoroethylene (PTFE) is modified by plasma radiation, and a diamond-like carbon film 12 is formed on the modified PTFE substrate 11 surface by chemical vapor deposition.
