Abstract

PURPOSE:To attain desired surface hardness, durability, thinness, and high rigidity by forming a Sn-Co layer on the surface of a substrate, and forming a carbon film on its surface. CONSTITUTION:Plating of a metal composition made of Sn: 60-65% and Co: 35-40% is applied to a nickel-electrocast outer edge 11 as backing treatment, and a Sn-Co layer 12 is formed on its surface 11a. Ion plating using the operating gas mixed with inactive gas and the gas having a benzene nucleus is applied to form a carbon film 13 on the surface 12a of the Sn-Co layer 12. When the nickel-electrocast outer edge 11 is used as a substrate, it can be made thinner. When an artificial diamond film is formed with the carbon film 13, a tip has high hardness, its tenacity is improved and higher rigidity can be attained.
