も大きな負荷がかかり、場合によっては変形が生じる。In the conventional brazing method,
Since the melting point of the copper alloy used is low, it is not possible to apply a high melting point brazing material having good bonding properties to the iron base material. In the case of joining using only silver brazing material, which is a low melting point brazing material, it is necessary to perform some surface treatment on the cast iron particularly when applying it to cast iron having poor wettability with the brazing material. When the wettability is improved by using a flux, the bonding surface is wide, so that a residual flux is generated, a non-bonded portion is easily generated, and the bonding strength is low. When the surface of the cast iron is plated to improve the wettability, the plating process complicates the construction process. Further, since the bonding strength between the plating and the cast iron is weak, it is difficult to obtain a strong bonding. Improving wettability by removing graphite from the surface of cast iron requires special equipment, complicates the construction process, and has a poor working environment such as using a salt bath. Even in the case of using silver brazing for low alloy steel or carbon steel, it is necessary to use flux or plating as appropriate. Further, in the conventional diffusion bonding method, a fine surface roughness is required for the bonding surface, and very laborious processing is required.
Furthermore, strict atmosphere control and high surface pressure are required for joining, and equipment and jigs become large. Also, a large load is applied to the swash plate support, and in some cases, deformation occurs.

す。EXAMPLES Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples, and can be implemented with appropriate modifications. Example 1 A foil-shaped (thickness: 0.1 mm) silver braze, foil-shaped (thickness: 0.05 mm) insert metal (made of Ni or Ni alloy) was placed on the sliding surface of a swash plate support made of spheroidal graphite cast iron. ), Foil (thickness 0.1mm)
2) Silver braze was placed in this order, and a copper alloy plate (made of high-strength brass having a thickness of 3 mm) having a shape corresponding to the shape of the sliding surface was placed thereon. On top of that, a holding jig that gives a surface pressure of about 0.005 MPa is installed, and in a vacuum furnace, in an N 2 gas atmosphere at 0.05 MPa,
It was heated to 880 ° C., which is higher than the melting point of silver solder. FIG. 7 shows the heat treatment pattern at this time. As a result, Ni in the insert metal and Fe in the swash plate support are mutually diffused through the liquid silver solder to form an Fe-Ni alloy layer, thereby obtaining a good bond between the copper alloy and the swash plate support. As a result, a copper alloy lining layer could be formed. Table 1 shows the results of the shear strength test. FIG. 8 shows a cross-sectional microstructure of a joint boundary when Ni is used as the insert metal.

(1) Ni, since use of Ni alloy, M n, insert metal comprising Mn alloy, carbon steel, low alloy steel, iron base material surface of the cast iron, Fe-Ni alloy layer, F e-Mn alloy layer Etc. occur. As a result, the wettability of the brazing material to the cast iron is improved and bonding becomes possible, and the bonding strength to carbon steel and the like is also improved. (2) At the time of joining, since the joining portion is filled with the molten brazing material, joining can be performed even if the surface roughness of the joining surface is not fine. (3) Since the diffusion of atoms is performed through the brazing material, which is a liquid phase, compared with the case where diffusion occurs directly between solid phases,
Bonding can be performed with a very small bonding surface pressure. For this reason, the joining jig may be simple, and the load on the base material is extremely reduced. (4) By joining in an inert gas atmosphere, it is possible to prevent the joint surface from being oxidized and improve the joining property, and also prevent the volatilization of the low melting point element in the brazing material and the copper alloy.
