Melting means using a high-density energy source by irradiation with an electron beam, a TIG arc or the like may be used. By using such a means, only the surface layer of the base material can be melted to reduce the thermal influence on the base material, and only a part of the base material can be locally alloyed. Generally, a laser beam is often used. Specifically, a YAG laser (wavelength 1.06 μm, pulse oscillation) or a CO 2 laser (wavelength 10.6 μm, continuous oscillation)
Is mainly used. In addition, melting may be performed on a portion requiring abrasion resistance, but when the portion covers a wide range, adjustment may be made by adjusting the oscillation width of a laser beam or the like or by sequential irradiation.

さらに金属と硬質粒子とを組合せても良い。The melting of the surface of the substrate is performed while supplying metal and hard particles from the outside of the substrate. Any metal can be used as long as it forms an intermetallic compound with Al by melting. As an example, each element such as Ni, Mn, Fe, Ti, V, Cr, Zr, Nb, Mo, Hf, and Ta can be cited. Further, it is not always necessary to use the metal alone, and it may be supplied in the form of an intermetallic compound and react with Al by melting to form an Al-based intermetallic compound.
On the other hand, examples of the hard particles include carbides such as TiC, WC, ZrC and NbC, nitrides such as TiN, ZrN and CrN, oxides such as Al 2 O 3 and other ceramics. These metals alone or hard particles may be used alone or in combination of two or more kinds of metals or hard particles.
Further, a combination of metal and hard particles may be used.

に応じて任意に設計すれば良い。Thus, in the reaction between the metal or hard particles and Al, one or two of B and Ge in the base material improve the wettability of the metal or hard particles to the base material, Promotes the reaction with Al. That is, when the base material does not contain B and Ge, the surface tension of the metal at the time of melting is large,
It is difficult to react with the base material. Hard particles also have poor wettability with the substrate. in this way,
B and Ge are mutually equivalent in terms of imparting a wettability improving effect, and it is sufficient that at least one of them is contained in the base material.
However, if the total amount is less than 1% by weight, the above effect is poor, and if it exceeds 30% by weight, the drawback is that the workability of rolling and extrusion of the base material is deteriorated. Therefore, the contents of B and Ge in the base material must be set to 1 to 30 wt% in total. The composition of the remainder other than B and Ge is not particularly limited, and various elements may be added and contained in order to retain the mechanical properties and processing characteristics required according to the application, or may be pure or pure. It may be based on aluminum. Also, the shape of the substrate may be arbitrarily designed according to the shape of the component to be applied.

ている。As one of the supply modes of the metal and the hard particles, there may be a case where a coating layer is previously formed on a predetermined site before irradiation with a laser beam or the like. The coating layer can be formed by wet plating, CVD, PVD, thermal spraying, or the like, or by applying a powder using various binders such as ethyl alcohol. Further, as another supply mode, a case where the powder is directly injected into the melting portion during irradiation with a laser beam or the like can be cited. Either method may be used, but in the case of the direct injection method, since the adjustment of the supply speed is troublesome, the coating method using a binder is excellent in terms of simplicity.

rAl 3 , NiAl, NiAl 3 , Ni 2 Al 3 , FeAl 3 , Fe 4 Al 13 , MnAl 6 ,
HfAl 3 , Nb: Al 3 , CrAl 7 and the like form an alloyed layer crystallized uniformly or densely. On the other hand, when the surface of the substrate is melted together with the hard particles, the particles are uniformly dispersed in the Al matrix or form an alloyed layer in which the particles are agglomerated. Thus, the above-mentioned intermetallic compound generally has a high hardness, and the hard particles themselves have excellent hardness, so that the alloyed layer exhibits high hardness as a whole, Has wear resistance. The thickness of the alloyed layer can be easily controlled from several tens of μm to several mm by changing irradiation conditions such as a laser beam, for example, output, irradiation speed, and focus position.
The harder the intermetallic compound and hard particles, the harder the alloying layer.

By locally melting the surface of an aluminum alloy substrate containing one or two types in a total range of 1 to 30 wt% together with a metal or hard particles supplied from the outside of the substrate, an Al matrix is formed into an Al matrix. Since the compound forms an extremely hard alloyed layer in which the compound is crystallized or hard particles are alloyed, the aluminum alloy material produced according to the present invention has remarkably excellent wear resistance, and is therefore suitable for automobiles and the like. It can be made suitable as a required wear-resistant part. Also, unlike the conventional surface treatment layer by plating or the like, since the alloying layer is integrally bonded to the base material, there is no danger of peeling of the layer even when used under a high surface pressure. And sufficient durability can be ensured.
