ど種々の問題があるものであった。In general, there are various methods for manufacturing composite metal members by metallurgically bonding metal members together, and among these methods, brazing is known as the simplest method. However, when at least one of the composite metal parts needs to be composed of a sintered alloy member, brazing is sometimes performed in such a way that the liquefied filler metal is absorbed into the internal pores of the sintered alloy member by capillary action. In some cases, a satisfactory bond between the members cannot be obtained. Therefore, it is necessary to perform pre-treatments on the sintered alloy members used as the composite steel before brazing, such as pore-crushing treatment and pore-filling treatment with an infiltrant, which results in high costs. In addition, there are various problems, such as the fact that depending on the blinding material or infiltration material, the properties of the sintered alloy member may be impaired.

分を０．５重量％以上含有するＦｅ基。Therefore, from the above-mentioned viewpoint, the present inventors created a composite sintered alloy member without performing blinding treatment or pore filling treatment, which were conventionally performed as a pretreatment when manufacturing a composite sintered alloy member.
One of the composite sintered alloy members, especially one of the composite sintered alloy members, is C'r, 'Mn, "" without using any brazing material.
V, "mb: Ti, Ta, and Zr
As a result of conducting research to manufacture a composite sintered alloy member composed of a sintered alloy member containing 0.5% or more of one or more of the components with extremely strong affinity for oxygen, such as Fe-based alloy containing 0.5% by weight or more of a component with extremely strong affinity for oxygen.

が得られるようになるという知見を得たのである。The N1-based or CO-based combustion alloy member 7 is prepared in such a manner that at least its joint surface contains 0.1 to 5.0% by weight of one or more of B, P, and Si. When a joint surface of a sintered metal member (a green compact member having a predetermined blending composition prepared separately is held in contact and heated in a liquid phase in this state, the green compact member is sintered and turns into a liquid phase). Since P, B, and 8i exhibit excellent wettability on the bonding surfaces of both components, these two components are strongly bonded, resulting in a composite sintered component with extremely high bonding strength. We obtained the knowledge that this is true.

のである。This invention was made based on the above knowledge, and contains 0.55% by weight of a component with extremely strong affinity for oxygen as an alloy component, and at least in the joint surface portion, among B, P, and sl. Fe group containing 0.1 to 5.0% by weight of one or more of the following:
Alternatively, a CO-based combustible alloy member and a green compact member having a predetermined composition are prepared, and liquid phase heating is performed with the green compact member being held in contact with the joint surface of the sintered alloy member. ,
The present invention is characterized by a method for manufacturing a composite sintered alloy member in which the compacted powder member is sintered and both members are integrally bonded.

量％と定めた。In addition, in the method of this invention, the reason why the content of P, B, and sl in the sintered alloy member is limited to 0.1 to 5.0% by weight is that if the content is less than 0.1%, the desired wettability cannot be secured at the joint surface, and therefore only a composite sintered alloy member with low joint strength can be obtained.On the other hand, if the content exceeds 5.0%, these components in the liquid phase will Since it protrudes from the joint surfaces of the members and reduces the product value, its content is set at 01 to 5.0% by weight.
