[Industrial Field of Application] The present invention relates to a method for economically manufacturing fin materials for radiators. [Prior art and its problems] Conventional fin materials for radiators include Sn and
A thin plate of Cu containing Cd is used. This is Cu
This takes advantage of the alloy's high thermal conductivity, good workability, and solderability. However, recently, corrosion of this fin material has caused a problem of decreased functionality and shortened lifespan of radiators.
This is most likely to occur in coastal areas where salt damage occurs due to sea salt particles or in cold regions where anti-freezing agents are sprayed, and the heat dissipation characteristics may deteriorate drastically within about two years after driving, leading to the end of the radiator's lifespan. According to the investigation, this corrosion resulted in the formation of a layer of Cu 2 O as an oxide film. To deal with this, the oxide film has good adhesion.
Cu alloys or Cu alloys that are difficult to form Cu 2 O have been developed, but because they are alloyed, they have drawbacks such as extremely impairing thermal conductivity, which is one of the important properties required for fin materials. There is. For example, Cu-Ni alloy has extremely high resistance to this type of corrosion, but its thermal conductivity is less than 1/10 that of pure copper, and its workability is also poor. Therefore, it has been desired to provide a fin material that has high thermal conductivity and excellent corrosion resistance. This can be achieved by providing a metal other than Cu and/or a diffusion layer of the metal on the surface of a material made of Cu or a Cu alloy. As a method for coating the surface of the material with a metal other than Cu, electrolytic or electroless plating, vapor deposition, sputtering, etc. can be used. Further, when forming a diffusion layer, heating is further performed in an inert or reducing atmosphere. This may be done immediately after coating the metal or after rolling after coating. However, electroplating and electroless plating require strict control of liquid composition and electrolytic conditions, and depending on the metal to be coated, a large amount of equipment costs are required, including waste liquid treatment. In addition, in melt plating, Zn,
Only limited metals such as Sn can be coated,
If it were to be applied to wide materials, it would require a huge amount of equipment. Furthermore, the efficiency of vapor deposition and sputtering becomes even worse. Therefore, with the prior art, there is a problem in itself in efficiently coating metal industrially, and if diffusion heating is added, there is a further problem in economic efficiency. [Object of the invention] The present invention solves the drawbacks of the prior art described above, and
The object of the present invention is to provide a method for economically producing a type of composite material that has improved functions such as corrosion resistance, strength, oxidation resistance, and solderability by coating and diffusing different metals on the surface of copper or copper alloy. [Summary of the Invention] The gist of the present invention is to provide a method for coating the surface of a material with a different metal in order to obtain a radiator fin material with excellent corrosion resistance and thermal conductivity. The method is to apply a mixture of metal powder and a liquid or paste substance having a flux action and then heat the mixture. Considering Cu and Cu alloys as radiator fin materials, metals that are practically effective as coating materials include Sn, Pb, Zn, Al, Ni, Au, Te,
Bi, Cd, Ga, and In are selected. However, a composition containing one or more of these as a main component can provide a practical coating effect, and therefore such a composition may be used. A liquid or paste substance mixed with such metal powder acts as an adhesive when applying the metal powder to the material surface, and also removes the oxide film and bonds the material surface with the molten metal. A material having a function of promoting wettability is used. Note that the metal powder component in the mixture is desirably 30% or more, since if this is small, it will be difficult to uniformly coat the surface of the strip material with metal. Further, as a method of applying the mixture,
Various methods are conceivable; for example, the mixture may be applied by continuously depositing the mixture on the surface of the rolls and passed between the rolls, or by providing a weir with an appropriate clearance above the strips. Alternatively, the mixture may be stored there and applied while moving the strip material at an appropriate speed. The upper limit of the heating temperature should theoretically be at most the melting point of the material, but practically it is preferably at least the melting point of the powder and granules and about 50° C. lower than the melting point of the material. The heating atmosphere includes air, N 2 , CO 2 ,
CO, H 2 , Ar gas, etc. are effective. In the case of an atmosphere other than the air, it is practically effective if at least 50% of one or more of the above gas components is contained. Coating and heating under the above conditions removes the oxide film on the surface of the material due to the fluxing substance mixed in the layer of the mixture applied to the surface of the material, and creates a bond between the surface of the material and the molten metal. Wettability is promoted and a coating layer of a dissimilar metal is formed on the surface of the material. In this case, a part of the diffusion layer is also formed. In order to promote diffusion and further alloying of the surface of the material, it is desirable to add a separate heating step. [Embodiments of the Invention] Examples of the present invention will be described below. FIG. 1 shows an example in which a coating layer 8 of a different metal is continuously formed on one side of a strip 1. A material 1 made of copper or a copper alloy is passed between upper and lower rolls 2 and coated on its surface. A thin layer 4 of a mixture of liquid flux and metal powder is applied. A mixture feeding device 3 is installed above the roll 2, from which the mixture is applied to the material 1 via the roll 2.
The thickness of the layer 4 of the mixture can be adjusted by the gap of the rolls 2. The material coated with a thin layer 4 of the mixture in this way is then heated in a heating device 5 in an inert gas atmosphere, passes through a flux washing device 6 and a drying device 7, and is passed through a thin coating layer 8 of a different metal on one side. The material is wound up by the winding machine 9 as a strip material having a . When forming the coating layer 8 on both sides, the roll 2
The mixture may also be applied to the lower roll. Next, a specific example will be explained. Example 1 A copper strip coil material with a thickness of 0.5 mm and a width of 450 mm was prepared, and by the method shown in Figure 1, ordinary liquid flux used for copper soldering and Sn powder were mixed in a ratio of 3:7. A paste-like mixture was applied by mixing the mixture in the following proportions to form a layer 4 of the mixture with a thickness of about 20 μm on one side. Subsequently, the sheet was continuously passed through a heating device 5 in an inert gas atmosphere, subjected to heat treatment at 500° C. for 90 seconds, passed through a water washing device 6 and a drying device 7, and wound up. As a result of detailed investigation of the surface of the obtained copper strip,
It was confirmed that a Cu-Sn alloy layer and a Sn coating were formed over a thickness of 2 to 3 μm. Corrosion resistance was determined using JIS
The salt water fog test was carried out for 30 minutes under the conditions specified in Z 2371.
The test was carried out for several days, and after removing corrosion products on the surface, the weight of the test piece was measured, and the weight loss before and after the test was determined and evaluated. Table 1 shows the results.

Example 2 Using the same method as in Example 1, a paste was prepared by mixing a powder containing Pb and Sn in a ratio of 7:3 and a liquid flux on one side of the same copper strip as in Example 1. A layer of the mixture was formed, heat treated at 500°C for 90 seconds, and rolled up. It was confirmed that a Pb-Sn alloy layer with a thickness of about 3 μm was formed on one side of the obtained copper strip. In a corrosion resistance test conducted with one side sealed, the one with a 5μ diffusion layer showed about three times the corrosion resistance of the one without a coating. Example 3 A mixture feeding device was also arranged in the lower roll part shown in FIG. A copper strip having the following properties was obtained. Both sides of the obtained copper strip have a Cu-Sn alloy layer and
It was confirmed that a Sn film was formed with a thickness of 2 to 3 μm. When the copper strip was subjected to the same corrosion test as in Example 1, it showed 2 to 3 times the corrosion resistance. [Effects of the Invention] The present invention applies a mixture of a metal powder and a liquid or paste substance having a flux action to the surface of a material made of copper or a copper alloy, and then heats it to melt the powder. Since this is a method of forming a metal coating and/or a diffusion alloy layer in this manner, it is easy to perform a series of steps continuously.
That is, a radiator fin material whose surface is coated with a different metal or alloy can be obtained easily and inexpensively. In particular, when obtaining an alloy film, electroplating requires a great deal of know-how such as adjusting the current density and controlling the liquid composition to obtain an alloy film with a predetermined concentration. This can be easily implemented by controlling the composition of the granules.
