摘要： PURPOSE: To make continuous production possible while a base material is held loaded in a reaction vessel by subjecting the surface of a sintered hard alloy base material to a heat treatment in an atmosphere where carbon atoms exist, cleaning the base material in a heated hydrogen atmosphere and forming diamond and/or diamond-like carbon by a vapor phase synthesis method on the surface of the base material. CONSTITUTION: A CVD apparatus shown in Fig. consists of a reaction vessel 1, an atmosphere gas introducing valve 2, a tungsten filament 3, a cooling base 4, the sintered hard alloy base material (e.g.: sintered hard chip of WC-25%Co) 5, and a gas discharge valve 6. The cobalt of the bond phase precipitates on the base material surface when the atmosphere gas is formed of H2 -1%CH4 , its pressure thereof is set under 100Torr and the base material is heated to 900 deg.C for 60 to 120 minutes. The base material is then exposed into the heated hydrogen atmosphere, by which the base material is subjected cleaning (pressure 100Torr and 900 deg.C). The atmosphere gas is changed over to H2 -1%CH4 and the diamond film is formed at >=10μm under the press of 100Torr and the base material temp. of 900 deg.C. The surface of the film is then polished.

摘要： PURPOSE:To reduce the adhesion of plating and improve molding precision, by constituting the part position of a tool which abuts against electronic member by using base material whose coefficient of thermal expansion is smaller than or equal to a specified value, and forming diamond or a diamond type carbon film on the base material surface by a vapor phase synthesis method. CONSTITUTION:Base material 6 having fixing holes 5 is formed by using material, like Si3N4 material, whose coefficient of thermal expansion is smaller than or equal to 5.5X10 . Diamond or diamond type carbon film is formed on the upper part of the base material which part contains an upper surface 22 turning to an abutting surface, by a vapor phase synthesis method. By constituting the abutting surface of a tool made of material whose adhesion to plating is very low, the adhesion of plating is reduced, and molding precision can be improved.

摘要： PURPOSE:To reproduce a drill in a simple work only by coating a rake face and a margin with diamond, keeping a flank without being diamond-coated. CONSTITUTION:Heat treatment is applied to a surface of a drill base material 1 in an atmosphere where carbon atoms exist to produce precipitates mainly comprising carbon and combined metals, and deposits mainly comprising carbon on the surface, and the deposits at specified parts of a rake face 5 and a margin 6 are eliminated. Next, in a chemical vapor phase synthesis method, diamond coating 2 is formed on the rake face 5 and the margin 6. Thickness of this coating 2 is set at about 10mum, and groove length is set at about 38mm. The coating is not applied on a flank 4. Hence, a drill can be polished easily even after use with a forward end of the drill on repolished as it is abraded, and life of the repolished drill is almost similar to that of a new one.

摘要： PURPOSE:To contrive improvement of the molding accuracy of an integrated circuit lead bending work use tool and increase in the production efficiency of the tool by a method wherein the contact surface of the tool is constituted of a diamond sintered body, which is hard, has a bad wettability with a plating, such as solder, and makes hard to generate adhesion of the plating to the contact surface of the tool, and the surface roughness of the contact surface is flat finished so as to prevent a deposit from being generated on the contact surface. CONSTITUTION:An integrated circuit lead bending work use tool consists of a die 2 and a punch. The die 2 is constituted by mounting integrally members 6, which has a soldered diamond sintered body piece D, to a die main body 21 by screws 7. The sintered body piece D is made by a method wherein a diamond sintered body layer A is provided on a carbide alloy base material layer B and the layer A is cut out at an angle Q of inclination and is formed into a sliding inclined plane 22. The surface roughness of the plane 22 is finished into a roughness of 0.03mum Ra or lower so as to prevent a deposit from being generated on the plane 22. Thereby, adhesion of a plating to the tool is very little, the molding accuracy of the tool is improved and at the same time, the frequency of production stops for a cleaning work is decreased and the production efficiency of the tool is increased.

摘要： PURPOSE:To obtain a material coated with a super-hard film in which the super-hard film is firmly fitted to a cermet base body by forming a diamond super hard film on the surface of a cermet preliminarily subjected to specified surface treatment. CONSTITUTION:This coated material consists of a base body and a super-hard film comprising diamond and/or diamond carbon formed on the surface of the base body. The base body is a cermet and its surface where a super-hard film is to be formed is preliminarily treated with >=1 kind of group III elements or compds. of these. The surface of the cermet base body is dipped in a fused liquid or solution of >=1 kind of group III elements or compds. of these. Then the super hard film comprising diamond and/or diamond carbon is formed on the treated surface by chemical vapor phase synthesizing method. By this method, fitting strength of the super-hard film is significantly improved so that a film over 20mum thickness which is conventionally impossible can be formed and polished. By polishing the film, the cuttability of the material can be further improved.
