摘要： PROBLEM TO BE SOLVED: To achieve a suitable recycling in a method of recycling cemented carbide with a high Co content using Zn decomposition method by suitably melting and diffusing melted Zn into Co and improving a recovery rate of the cemented carbide.SOLUTION: When melting and diffusing cemented carbide granules containing WC as a principal component and Co as a binder component into the melted Zn, the cemented carbide granules are made easier to be infiltrated into the melted Zn by pressurizing the melted Zn housed in a crucible at a temperature at which Co and Zn change into a liquid phase under a Co-Zn constitutional diagram, and the melted Zn in the crucible is convected so as to be suitably melted and diffused into the cemented carbide granules by moving up and down or vibrating by falling the melted Zn. As a result, compared with conventional methods, more melted Zn is melted and diffused into Co and the recovery rate of the cemented carbide granules improves, thereby enabling the suitable recycling.

摘要： PROBLEM TO BE SOLVED: To provide a rotary tool having long service life even to a metallic material whose welding or surface reforming is difficult.
SOLUTION: A WC-Ni-Cr-based material is used as a material for a rotary tool 100a. The high-temperature stabilized phase of iron is austenite, the crystal structure is body-centered cubic crystal. The crystal structure of Ni is similar thereto, and excellent high-temperature strength can be obtained by using Ni for the metal phase. Further, in the Ni-Cr phase with Cr subjected to solid solution, the strength is increased by enhancing the solid solution, and excellent characteristics are shown such as thermal stress, oxidation resistance, and corrosion resistance. As a result, in the WC-Ni-Cr-based alloy, deposition resistance is considerably improved in comparison with that of a WC-Co-based alloy. Thus, the friction resistance caused during the friction stir welding is stabilized, and accordingly, stress concentration (friction resistance+bending stress) due to any unexpected increase in friction resistance during the welding is avoided, and any breakage of the rotary tool 100a can be prevented.
