METAL MATERIAL MACHINING METHOD, AND STRUCTURE AND ROTARY TOOL MACHINED USING METAL MATERIAL MACHINING METHOD

摘要

the probe 12 of the rotary tool (10a) is Ir, Mo, W, V and those of an alloy containing at least 50% by weight, and the shoulder 11 is Si ₃ N ₄ and had been made of ceramics such as polycrystalline cubic boron nitride. Thereby, abrasion resistance and metal for the probe 12 (1, 2) due to the high adhesion of the like, rigid metallic material (1, 2) to improve the life of the rotary tool (10a) in the case of bonding, the bonding to improve the stirring portion corrosion resistance, it is possible to promote the stirring of the joint (3). In addition, the shoulder (11) for wear resistance and a metallic material (1, 2) due to the high adhesion of the like, the surface of which is roughened to prevent the shoulder (11) after passing through the junction (3), for bonding the stainless steel If it is possible to improve the corrosion resistance of the joint in (3). ;
