Method of producing coated member

摘要

A production method of a coated member (20) is performed in the following way. First, a diamond-like carbon film deposition process in which the diamond-like carbon film (21) is formed on a surface of the base material (4) by generating plasma by applying voltage to the base material (4) in a processing chamber (3) that stores the base material (4), while evacuating the processing chamber (3) and introducing feedstock gas that contains at least a carbon compound into the processing chamber (3). After this, a hydrogenation process in which the deposited diamond-like carbon film (21) is hydrogenated using hydrogen gas by stopping the voltage application and introducing hydrogen gas inducted instead of the feedstock gas, while the evacuation is being continued.
