Description of the Related Art Conventionally, Al or Al alloy has been used in a wide range of fields including automobile parts because it is lighter in weight and excellent in heat conductivity and corrosion resistance as compared with steel materials. However, Al alloys generally have higher strength, wear resistance, and
It is inferior in heat resistance, and if the Al alloy material is as it is,
The parts and parts that can be applied as substitute materials for steel materials are limited. Further, even when Al or Al alloy is already used, in recent years, further improvement in durability is required as the use environment becomes severe. As a countermeasure, in addition to the improvement of the Al alloy itself, a method of forming a wear resistant and heat resistant layer on the surface is used. For example, there are a method of forming a thin hard coating layer by PVD and CVD, and a method of forming a relatively thick hard coating layer by thermal spraying. However, the film formed by these methods is very hard, but the adhesion to the base material is weak, and there is a risk of peeling or falling off during use, resulting in poor reliability. Furthermore, PVD and CVD have a low film formation rate, and it is difficult to form a thick film. In the case of thermal spraying, there are problems in terms of environment such as generation of noise and light rays, and there is a problem that the adhesion to the substrate is low and peeling occurs during use. On the other hand, there is disclosed a method of forming a hard alloy layer by melting an alloying metal together with the surface of a base material using a high-density energy source such as an electron beam, a laser and an arc. By these methods, a hard layer having a certain degree of hardness can be formed. For example, in Japanese Patent Laid-Open No. 55-27587, V, Cr, Mn, Fe, Co, etc., applied to an Al alloy piston by an electron beam,
An alloying treatment technique of Ni is disclosed. Japanese Utility Model Laid-Open No. 62-72456, Japanese Utility Model Laid-Open No. 62-72458 also discloses a Cu alloying technique using an electron beam. Also, JP-A-61-166982 and JP-A-61-1705
Japanese Patent No. 78 discloses a technique for alloying Ni and Fe by TIG arc. Japanese Unexamined Patent Publication (Kokai) No. 64-11073 also discloses a technique for alloying Cu with an arc. In Japanese Patent Laid-Open No. 58-179569, Al or Al alloy powder and NbC powder, TiC powder, V
A method for surface hardening an Al-based material by TIG arc using a mixed powder with C powder is disclosed.

マアーク肉盛溶接用溶加材を提供することにある。Similar to the present invention, these alloying treatment techniques have a high joining force and are promising because the base material and the treatment layer are metallurgically bonded to each other. There is a problem. (1) Similar to the present invention, the above-mentioned alloying technique uses Al of the base material,
The surface of the Al alloy is melted and a metal is added from the outside to form an alloy layer. However, when the addition method, conditions, and welding heat input conditions change, the melting amounts of Al and Al alloy of the base material change, which causes a change in the obtained alloy layer composition. In particular, when powder is used as the filler material, there are problems such as stable feeding of the filler material and segregation of the composition, and it is difficult to obtain an alloy layer having a uniform composition. For example, in a mixed powder of ceramics such as NbC and TiC powders and Al alloy powder, ceramics such as carbides are generally crushed powders and thus are irregular shaped powders, stable feeding is difficult, and mixed powders having different specific gravities are A compositionally uniform feed is difficult. Therefore, since the dilution amount of the added metal varies, the composition of the obtained alloy layer becomes non-uniform,
This causes fluctuations in properties such as wear resistance and heat resistance. (2) Usually, the metal added for alloying is A of the base material.
It is difficult to form a uniform alloy layer because it has a higher melting point than that of the Al alloy. If an electron beam with a high density of energy is used, an alloyed metal having a high melting point can be easily melted and a uniform alloy layer can be obtained. However, since the alloying treatment by electron beam is performed in a vacuum container, Al, Al
If the alloy is overheated, blowholes and pits are likely to occur and productivity is low. A laser has a high energy density like an electron beam, but for Al and Al alloys,
Not suitable because of low absorption rate. Further, since the electron beam and laser devices are expensive, the cost of the applicable parts is high. (3) When welding Al and Al alloys, H
2 , H 2 O, N 2, etc. are easily occluded, welding defects such as pits and blow holes are easily generated, and the gas component brought from the filler metal is a major factor in the generation thereof. Metal powder such as Al alloy powder is generally produced by the gas atomizing method or the water atomizing method, and contains a large amount of gas as shown in Table 1 as compared with the solid wire. Therefore, when a metal powder such as an Al alloy powder is used as the filler, there is a problem that welding defects such as blow holes and pits are likely to occur due to the gas contained in the powder. The present invention has been made to solve the problems of the alloying treatment as described above, and its object is to use a wire containing a small amount of gas in the filler metal on the surface of the Al-based material. As a result, welding defects such as pits and blowholes do not occur, wear resistance with high bondability to the base material, heat resistant alloying layer is stable, gas shield arc, plasma arc overlay that can be obtained at low cost To provide a filler metal for welding.

In the arc generated between the l-base material base material and the non-consumable electrode, the filler material plated with Al metal is fed to the surface of the wire material made of the Cu-based material, or the surface of the wire material made of the Cu-based material By feeding a consumable electrode plated with Al metal to the Al, an alloyed layer containing Cu can be formed on the surface of the Al-based material. Specifically, a build-up material for forming a wear-resistant / heat-resistant alloyed layer on the surface of an Al-based material was examined. As a result, the desired wear resistance and heat resistance can be stably obtained, and further,
It has been found that it is desirable to apply Al plating to Cu or Cu alloy wire from the viewpoint of economical efficiency, manufacturability (drawability) and the like. Further, the hardness of the alloyed overlay obtained in this case is required to be Vickers hardness Hv150 or more from the viewpoint of wear resistance, and if it is less than Hv150, improvement of wear resistance is not expected. The structure of the overlay layer made of the Al-plated Cu-based material as the filler is composed of an α phase and a θ phase (CuAl 2 ) on the high Al side, and due to the existence of the θ phase, it has wear resistance and heat resistance. That is, when the Al plating amount exceeds 85%,
Since the amount of Cu in the overlay obtained by welding is insufficient,
Only the phases are present, and the hardness does not reach Hv150, which is not suitable for wear resistant materials. On the other hand, when the Al plating amount is less than 50%, a brittle η 2 phase appears and cracking occurs. Therefore,
Al plating Cu-based filler material has an Al plating amount of 50-
It must be within the range of 85%. FIG. 1 is a diagram showing a manufacturing process of an Al-plated Cu-based filler metal according to an embodiment of the present invention. The method for producing an Al-plated Cu-based filler material according to the present invention comprises a Cu-based wire, if necessary, an appropriate wire drawing,
After annealing and pickling, the surface of the Cu-based wire is plated with a predetermined amount of Al, and then wire drawing is performed to a finished size, and then wound on a reel. In this case, hot dipping is adopted as the plating means. In addition, the Cu-based wire of the core wire of this filler material is an alloy element of an ordinary Cu alloy, such as S.
i, Ni, Sn, Mn, P, Zn, Fe, Al and the like may be contained in a range that does not affect toughness and wire drawability.
