Abstract
A method of smoothing a surface of a diamond coating of a diamond-coated body, by using an arc-type ion plating device in which at least one target is disposed. The method includes: (a) a step of causing arc discharge between an anode, and a cathode which is provided by each of the above-described at least one target, whereby positive ions are emitted from the above-described at least one target; and (b) a step of applying a negative bias voltage to the diamond-coated body which is disposed in the arc-type ion plating device, whereby the surface of the diamond coating is bombarded with the positive Lions, so as to be smoothed by the bombardment of the positive ions against the surface of the diamond coating.
