[Industrial Field of Application] The present invention relates to a surface treatment method for melt-bonding an inorganic material such as alloy steel, non-ferrous metal, glass, or ceramics onto the surface of a base material made of steel (including alloy steel). [Prior Art] Steel has excellent workability, strength, and economic efficiency, and is widely used in various industrial fields. These properties of steel are
This is something that cannot be obtained with non-ferrous metals, glass, ceramics, or other inorganic materials, but on the other hand, non-ferrous metals and inorganic materials have various properties that cannot be obtained with steel. For example, ceramics have better heat resistance, rust prevention, wear resistance, etc. than steel. For this reason, so-called composite materials, which combine the properties of steel by joining different materials with properties different from those of steel, have been attracting attention in recent years, and fusion joining is known as one of the joining methods. There is. Some examples of fusion welding will be explained below, taking as an example the case of joining ceramics to steel. Γ Brazing Metallization brazing is generally used for brazing steel and ceramics. This is a method in which ceramics with a metallized surface are joined with silver solder or the like to steel whose surface has been activated by surface treatment such as blasting or chemical conversion treatment. Similar to this, a method is also known in which an intermediate layer of Al alloy is interposed between surface-activated steel and surface-metallized ceramics, and the two are joined by melting the intermediate layer. . Γ Diffusion Bonding An insert metal with a thickness of approximately 10 to 100 μm is sandwiched between a base-treated steel surface and metallized ceramics, and the two are diffusion bonded by heating and pressurizing. In addition to using foil or powder, the insert metal may be formed directly on the surface of the steel base material by electroplating, vapor deposition, ion plating, or the like. Note that diffusion bonding includes those that involve a liquid phase in the bonding process and those that do not involve a liquid phase, but those that do not involve a liquid phase do not belong to the fusion bonding that is the object of the present invention. Γ Thermal spraying is a method in which ceramics are fed into a high-temperature, high-velocity jet and sprayed onto the steel surface. usually,
The steel surface is previously subjected to surface treatment such as blasting. Water plasma, gas plasma, combustion gas, arc, etc. are used as the jet. The ceramics supplied in the jet is melted and then cooled, but due to supercooling, it reaches the steel surface in a liquid phase to form a ceramic bonding layer. [Problems to be solved by the invention] By the way, when joining dissimilar materials to steel by fusion joining such as brazing, diffusion joining, thermal spraying, and even vapor deposition, as mentioned above, it is difficult to join the steel base material during joining. Various surface treatments are applied to the surface. Commonly used surface treatments include pickling, blasting, and chemical conversion treatments, but in addition to these, metals with compositions appropriate for the filler metal and insert metal can be applied to the surface of the steel base material by electroplating, vapor deposition, ion blating, etc. It is attached as appropriate. However, it has been found that such conventional surface treatment does not sufficiently increase the bonding strength to the steel base material. The present invention provides a surface treatment method capable of imparting high bonding strength to a steel base material when melting and bonding dissimilar materials such as ceramics to steel. Melt bonding in the present invention refers to dissimilar materials to be joined to the surface of a steel base material, which are brought into contact with the surface of the steel base material through an intermediate layer in a molten state or by making the dissimilar materials themselves into a molten state. , refers to the joining of dissimilar materials to the surface of a steel base material by solidifying them, and the molten state includes a state in which the material is in a liquid phase even if the temperature is below the melting point due to supercooling. Melt bonding through an intermediate layer in a molten state includes brazing, liquid phase diffusion bonding, etc. Melt bonding in which dissimilar materials themselves are separated by thermal spraying,
There are vapor deposition, a combination of CIP and firing, HIP, etc. [Means for Solving the Problems] In the surface treatment method of the present invention, at least the outer surface of the steel base material is made of zinc, aluminum or an alloy thereof as a surface treatment when dissimilar materials are melt-joined to steel. or after forming a plating layer of zinc, aluminum or other metals, projecting particles whose at least the outer surface is made of zinc, aluminum or an alloy of these metals onto the plating layer. It is. Here, the particles whose at least outer surface is made of zinc, aluminum, or an alloy thereof refer to Zn, Al
or an alloy thereof, or a powder having a core of iron or an iron alloy and whose surface is coated with Zn, Al, or an alloy thereof. In addition, the alloy mentioned here specifically refers to Zn.
-Fe, Zn-Al, Zn-Mn, etc. [Operation] When iron alloy grains having, for example, a Fe-Zn alloy coating are projected onto the surface of a steel base material, an iron alloy coating having the same composition as the projected iron alloy grains is formed on the surface of the steel base material.
A typical example of this process is Z-blasting in dry plating called Z-S process, and the film formed by this Z-blasting process has 2
It is thin at ~10 μm, porous, and stably exhibits an uneven state with a surface roughness Rmax of 5 to 20 μm. When dissimilar materials are fused and bonded to the surface of a steel base material on which such a film has been formed as a base, the molten filler metal blends well with the base, and the solidified filler metal has an anchoring effect on the base. Bonds with high strength due to fastener effect. Similarly, in the case of diffusion bonding, the insert metal, and in the case of thermal spraying, the material to be bonded, such as ceramics, adapts well to the base and exhibits an anchor effect or fastener effect, resulting in a strong bond. Furthermore, such a base treatment film itself becomes the insert metal, and this aspect also contributes to improving the bonding strength. By the way, in the case of blasting, conventional surface treatment merely forms irregularities on the surface of the steel base material, but does not make it porous, and compared to the method of the present invention, the compatibility with the molten material is significantly inferior. . Even when a film is formed by electroplating or the like, the surface of the film is flat and dense, and physical bonding with the molten material as in the method of the present invention cannot be expected. Therefore, in any of the surface treatments, the bonding strength to the steel base material is significantly inferior compared to the method of the present invention. The projection base coating according to the present invention exhibits the same effect when coated not only on the surface of a steel base material but also on the surface of a plating layer coated on the surface of a steel base material. [Example] Hereinafter, the method of the present invention will be described in detail in the order of projection onto a steel base material, projection onto a plating layer, and specific examples. Projection onto Γ steel base material For example, iron alloy particles are projected onto the surface of the steel base material. Iron alloy grains are, for example, shot grains used in Z-S processing, and typical examples are Fe-Zn alloy grains, Fe-Zn alloy coated grains, Fe-Zn-Al alloy grains, or Fe-Zn-Al alloy grains. These are alloy coated grains. Since Z-S processing itself is a well-known dry plating method, various conditions such as the specific composition of the alloy, particle size, and projection speed may be appropriately selected from within the range of well-known Z-S processing conditions. However, when selecting the alloy composition, it is necessary to consider compositional compatibility with the molten material, etc., since the projection-formed coating may also serve as the insert metal. The method of the present invention has found excellent suitability for the blasting process of this well-known dry plating method as a base treatment during melt bonding. Table 1 summarizes the projection conditions normally used for round bars and the like.

る。[Table] When the surroundings of the joint members are in a corrosive environment and there is a risk that corrosion of the steel base material may progress from the joint interface, the iron alloy coating formed by the projection of iron alloy particles should be treated with chromate or phosphorus. It is preferable to perform chemical conversion treatment such as acid treatment. As mentioned above, the film formed by projecting the iron alloy particles is porous, highly impregnable with the chemical conversion treatment solution, and provides high corrosion resistance to the bonding interface with the steel base material. Projection treatment on the Γ plating layer Projection is performed on the surface of the plating layer coated on the surface of the steel base material. For the plating layer, zinc, aluminum, or a zinc-aluminum alloy is selected in consideration of its compatibility with the molten material. In order to obtain a uniform thin film, plating is performed by electroplating, melt plating, etc., and the plating thickness is preferably 10 to 150 μm. The particles to be projected onto the plating layer are particles whose at least outer surface is made of Zn, Al, or an alloy thereof. For example, when projecting with Fe-Zn alloy particles, the surface of the plating layer is porous and has an uneven surface.
A Fe-Zn alloy layer is formed. In this case, the plating layer and the projection coating may be made of the same metal or may be made of different metals. In the case of Fe-Zn alloy grains, the grain size is preferably about 0.2 to 1.5 mm. In this case as well, the chemical conversion treatment after projection is effective in suppressing corrosion from the bonding interface with the steel base material. Preferred combinations of projection and chemical conversion treatment in the method of the present invention are illustrated in Tables 2 () to ().
