Abstract
PURPOSE:To develop the material for a cemented carbide tool which has high fracture toughness value and is excellent in adhesion of a base body and a hard carbon-base film by forming the hard carbon-base film on the surface of the base body made of fine ceramic reinforced with specified inorganic fiber. CONSTITUTION:SiC whisker having 0.1-1,0mum diameter, 5.0-100mum length and 20-200 aspect ratio is mixed with fine powder of fine ceramic such as alumina having <3.0mum average particle diameter at a ratio of about 4:1 weight ratio. A base body made of fiber-reinforced fine ceramic wherein the alumina matrix is hardened with SiC whisker is produced by packing the mixture to the inside of a molding die and thereafter sintering it e.g. at about 1500 deg.C with a hot-press method. This is introduced into the atmosphere of the gaseous mixture of both hydrocarbon-base gas such as methane, ethane and propane and the gas for dilution such as H2, He and Ar, and the material for a cemented carbide tool excellent in toughness is produced by exciting gaseous hydrocarbon with a high-frequency plasma CVD or the like and depositing superhard diamondlike carbon on the surface of the base body made of fine ceramic with strong adhesive force.
