摘要： PROBLEM TO BE SOLVED: To provide a treating method by which the wettability of a carbon nanomaterial can be improved for the purpose of uniformly dispersing the carbon nanomaterial into a molten metal.
SOLUTION: The treating method comprises a process for mixing a metal powder 12 containing an element, which forms a compound by the reaction with carbon, with a carbon nanomaterial 11, and a vapor deposition process comprising charging the obtained mixture 15 into a vacuum furnace 20, then evaporating the metal powder 12 under high temperature and vacuum conditions, and depositing the vapor onto the surface of the carbon nanomaterial 11. Thereby, the metal particles form the compound with carbon, and the formed compound exhibits bonding action. Accordingly, each metal fine particle strongly bonds to the carbon nanomaterial 11. When the carbon nanomaterial is mixed with the molten metal, the carbon nanomaterial is uniformly dispersed in the molten metal because each metal fine particle has high wettability with the molten metal.

The N type elements are subjected to removal of oxide film and chemical polishing in the second half of etching process. The P type elements are subjected to dissolution of formed oxide film and chemical polishing. Subsequently, black oxide film formed immediately after etching is cleaned ultrasonically in alkaline solution and removed in desmut process. Finally, chemical nickel plating is performed following to sensitizing/activating process.

摘要： PURPOSE:To provide a highly durable forging die by preventing the ceramics die from being destroyed during the forging operation, and provide a forging die to make effective use of the characteristics of ceramics. CONSTITUTION:In a forging die where a die part to forge a work is made a ceramics die 20, and the ceramics die to clamp and support the ceramics die 20 by a clamed die 22 is used, the ceramics die 20 is clasped and supported by the clamped die 22 by the minimum clamping force required to clamp and support the ceramics die 20 in the actual forging operation for the ceramics die 20. The clamped die 22 is formed large enough to prevent the shock force exerting on the clamped die 22 from being exerted on the ceramics die 20 as the excessive load to the applying force of the ceramics die 20 to be required to forge the work.

摘要： PROBLEM TO BE SOLVED: To provide a surface treatment mold of a material equivalent to generally, widely used SKD 61 in which seizure resistance and the mold releasability of the object to be molded are improved, and the improvement of the service life and the reduction of a release agent sprayed on molding to be used are possible by reducing the wettability between its surface and the molten metal of magnesium in die casting or injection molding for a magnesium alloy.
SOLUTION: The surface of a mold for die casting or injection molding to a magnesium material, formed of a material equivalent to SKD 61 is subjected to gas nitrosulfurizing treatment under suitable conditions. Thus, a sulfide layer having excellent adhesion with a base material and low wettability with the molten metal of magnesium is formed on the outermost surface of the mold without requiring a complicated process.
