| description | PROBLEM TO BE SOLVED: To provide a method for producing a sintering diffusion joining member, capable of improving a joining strength between the pressed powder member formed by compressing metal powder and a metal member.SOLUTION: A method comprises: a step S102 of compressing metal powder filled in a press-forming portion to preform a pressed powder member; a step S103 of thereafter sliding the preformed pressed powder member and a metal member to each other, in which an oxide film formed on an outer wall of the metal member and impurities adhered to the outer wall thereof are removed by the metal powder in a surface where the pressed powder member and the metal member are slid, and then the surface profile of the metal powder is transferred to the outer wall of the metal member; a step S104 of further pressurizing the pressed powder member to temporarily join the pressed powder member and the metal member; a step S 105 of thereafter sintering the pressed powder member and the metal member which are temporarily joined, in a sintering furnace to join the pressed powder member and the metal member by sintering diffusion. Thus, joining areas between the pressed powder member and the metal member are increased, thereby improving a joining strength.
【課題】 金属粉末を圧縮し成形される圧粉部材と金属部材との接合強度を向上する焼結拡散接合部材の製造方法を提供する。【解決手段】 Ｓ１０２において、加圧成形部に充填された金属粉末を圧縮し圧粉部材を予備成形した後、Ｓ１０３において、予備成形された圧粉部材と金属部材とを摺動させる。このとき、圧粉部材と金属部材とが摺動する面では、金属部材の外壁に形成されている酸化膜や金属部材の外壁に付着している不純物が金属粉末によって除去されるとともに、金属粉末の表面形状が金属部材の外壁に転写される。Ｓ１０４において、圧粉部材をさらに加圧し圧粉部材と金属部材とを仮接合した後、Ｓ１０５において、仮接合された圧粉部材と金属部材とを焼結炉において焼結し、圧粉部材と金属部材とを焼結拡散接合する。これにより、圧粉部材と金属部材との接合面積を大きくし接合強度を向上することができる。【選択図】 図２ |
