    Publication number: 20060151433
    Abstract: The invention relates to a method for removing and recoating of diamond-like carbon films and its products thereof. The method is to immerse the units that are coated with diamond-like carbon films into the hydrogen chloride solution to come off the coating, which was located on the units' surface. In addition, the method can effectively improve the past fault of poor adhesion, resulting from excessive residual stress and damaged unit surface due to the conventional sandblasting film removing process.
