Manufacture of diamond-coated member

Abstract

Abstract PURPOSE:To manufacture a diamond-coated member excellent in reproducibility and uniformity by subjecting a base material to ultrasonic grinding by the use of an abrasive liquor in which diamond grains are dispersed and a surfactant is mixed and then applying coating to the above by a CVD method. CONSTITUTION:After pretreatment of ultrasonic grinding is applied to a base material, diamond coating is applied to the above by a CVD method. In the above method, a liquor prepared by further mixing a surfactant into a dispersed solution in which diamond grains are dispersed into turpentine oil, etc., is used as an abrasive liquor for the above ultrasonic grinding. Moreover, it is preferable to mechanically agitating the above abrasive liquor at the time of ultrasonic grinding. By this method, the distribution of the diamond grains in the abrasive liquor is uniformized, by which the diamond-coated material can be obtained with superior reproducibility and uniformity, and further, grinding time can be shortened.
