[Industrial Field of Application] The present invention relates to a method for manufacturing a bonded product of an iron-based sintered body and a copper-based sintered body having strong and stable bonding strength. Such bonded products include, for example, composite bearings with an oil-retaining copper-based sintered body on the inside and a high-strength iron-based sintered body on the outside; It is useful as a special stepping motor cover that takes advantage of the non-magnetic properties of the solid. [Conventional technology] Conventionally, in order to manufacture such combination parts of iron-based materials and copper-based materials, brazing, caulking,
Methods such as shrink fitting are common, but they pose problems in terms of mass production and cost. [Problems to be Solved by the Invention] Therefore, the present inventors focused on joining, which is superior in mass production and reduces costs, and developed an iron-based sintered body with a porosity of about 15% and a pure copper-based When we examined the bonding strength by abutting the sintered body at the joint and heating it to various temperatures, we found that the bonding strength was low and unstable if only heated to a low temperature (there was large variation between products).
To solve this problem, heating at even higher temperatures resulted in problems such as significant deformation of the copper-based components. Therefore, an object of the present invention is to provide a method for manufacturing a bonded product of iron-based materials and copper-based materials that has high bonding strength and is stable without deforming the copper-based components by heating and bonding. It is. [Means for Solving the Problems] As a result of various studies, the present inventors have obtained the following knowledge. (a) If the iron-based material is made into a sintered part with a porosity of 5 to 20% by volume, and one or two of P and Sn are added to the copper-based material, during heating for bonding, One or two of P and Sn
A melt with Cu is generated, which penetrates into the pores in the iron-based sintered parts, resulting in a strong and stable bond. Since the shrinkage rate from the molded product exceeds 2%, making it difficult to control the dimensions, adding C to a copper-based material containing one or two of P and Sn will suppress the shrinkage. , the shrinkage rate should be 2% or less, C. When higher hardness is required for the copper-based part, for example, when the bonded product is used as a composite bearing, it is effective to add Zn. (d) When self-lubricating properties are required in the copper-based parts, for example, when the joined product is used as a composite bearing, it is effective to further add Pb. This invention was invented based on the above findings, and includes: an iron-based sintered body having a porosity of 5 to 20% by volume; and one of P: 0.5 to 1.5% and Sn: 5 to 1.5%. A composition consisting of one or two species, C: 0.2 to 2%, one or two of Zn: 0.1 to 20% and Pb: 0.1 to 3%, Cu and unavoidable impurities: the remainder (or more) % by weight) with a copper-based sintered body or green compact at the joint, and heated to 700 to 1000℃.
This is a method for manufacturing a joined product of an iron-based sintered body and a copper-based sintered body, which is characterized in that the joining is performed by heating to a temperature within the range of . The configuration of this invention will be explained below. Porosity of iron-based sintered body If the porosity is less than 5% by volume, the melt of one or two of P and Sn and Cu will not penetrate sufficiently into the inside of the iron-based sintered body, resulting in poor bonding strength. On the other hand, if it exceeds 20% by volume, the strength of the iron-based sintered body portion decreases, so the porosity of the iron-based sintered body was set at 5 to 20% by volume. Copper-based sintered body or green compact i Composition a P and Sn These components react with Cu to produce a melt,
It contributes to the increase and stability of the bonding strength with the iron-based sintered body, and also has the effect of increasing the hardness, but if the content of these is less than 0.5% by weight of P and less than 5% by weight of Sn, the liquid P: 1.5% by weight, respectively.
Sn: If it exceeds 15% by weight, the amount of liquid phase will become too large and the shape of the copper-based sintered body used for bonding or the copper-based sintered body obtained as a result of heating and bonding may collapse, or the carbon content may become too large. Even if added, the shrinkage rate would exceed 2%, so the content of P was determined to be 0.5 to 1.5% by weight, and the content of Sn was determined to be 5 to 15% by weight. b C C has the effect of reducing the wettability between the melt and Cu, suppressing the shrinkage of the copper-based sintered body, and facilitating dimensional control, but if the amount is less than 0.2% by weight, the desired effect is not achieved. On the other hand, if the content exceeds 2% by weight, the sinterability will be too low and the strength of the copper-based sintered body will decrease, so the content was set at 0.2 to 2% by weight. . c Zn Zn also forms a solid solution with Cu to increase hardness, so
It is added as needed, but the amount is 0.1% by weight.
If it is less than 20% by weight, the hardness will not be sufficient, while if it exceeds 20% by weight, the volatilization of Zn during sintering or joining will be severe, and even if the copper-based material used for joining is a compact, or the sintered Even if the copper-based sintered body is bonded, the resulting copper-based sintered body will have more pores and become brittle, so the content was set at 0.1 to 20% by weight. d Pb Pb imparts lubricity to copper-based alloys, so it is added as necessary when joining products of iron-based sintered bodies and copper-based sintered bodies, for example, in sliding parts such as bearings. However, if the amount is less than 0.1% by weight, the desired effect cannot be obtained, while if the content exceeds 3% by weight, the strength of the copper-based sintered body portion will decrease. The content was determined to be 0.1 to 3% by weight. Powder compact or sintered compact The copper-based material used for heating and bonding may be a compact or a sintered compact as long as it produces a melt during bonding. Heating/Joining One or two of P and Sn can be bonded by heating.
A melt of the seeds and Cu is generated, and the melt penetrates from the copper alloy sintered body or green compact through the joint (the part to be joined) into the pores of the iron-based sintered body, A strong and stable bond is created, and when a green compact is used, it is also sintered at the same time.
If the temperature is lower than 700℃, the amount of liquid phase will be small and the bonding strength will be insufficient.On the other hand, if the temperature exceeds 1000℃, the copper alloy part will become too soft and the amount of deformation will increase, so the heating temperature should be reduced to 700℃. The temperature was set within the range of ~1000℃. [Example] Example -100 mesh electrolytic iron powder, -100 mesh Fe
-18% Cr-2% Ni atomized powder, -200 mesh graphite powder, -100 mesh electrolytic copper powder, -
100 mesh Cu-9%P atomized powder, -100 mesh Cu-30% Zn atomized powder, -100 mesh Cu-20% Sn atomized powder, -100 mesh
Prepare Pb atomized powder, mix these powders so that they have the composition shown in a and b in Table 1, and then press the iron-based material at a pressure of 5 ton/cm 2
The copper material was pressed into a circular plate with a diameter of 20 mm x 10 mm thick, and the copper material was made into a square plate with a length of 10 mm x width of 10 mm x 5 mm of thickness using a press pressure of 5 tons/cm 2.

As is clear from Table 2, the products joined by the method of the present invention have high and stable shear strength at the joint, and the shrinkage rate of the copper-based material part is small, making it easy to control dimensions. If E is used, the porosity of which is higher than the range of the present invention, the iron material will be damaged during the shear strength measurement, and conversely, if F, which has a porosity that is too low, is used, the melt will be damaged. It did not penetrate sufficiently and its strength was low. On the other hand, when copper-based materials 21 and 23 are used, in which the amounts of P and Sn are lower than the range of the present invention, the strength is low, and when 22 and 24, in which the amounts of P and Sn are too large, are used, the amount of melt is large. This caused the shape of the copper-based material to collapse. In addition, when a copper-based material 25 with a lower C content than the range of the present invention is used, the strength is high but the shrinkage rate is large, and when a copper-based material 26 with an excessive amount of C is used, the copper-based material 25 is used when measuring the strength. The material part was damaged and the shear strength of the joint could not be measured. In combination B-27, which uses 27 copper-based materials that do not contain P or Sn, the bonding strength is low;
The variation is also large. Therefore, according to the method of the present invention, composite parts having high and stable bonding strength as described above and high precision can be produced in large quantities at low cost.
