大きな障害となっていた。Conventional Technologies and Problems As is well known, aluminum or aluminum alloys are much lighter than commonly used iron-based materials, and have excellent thermal conductivity and corrosion resistance. It has come to be widely used in various mechanical parts such as automobiles. However, aluminum or aluminum alloys generally have inferior wear resistance compared to iron-based materials, and this has been a major obstacle when replacing iron-based parts with A4 alloy parts for the purpose of reducing weight in automobiles, etc. .

いという欠点があった。Therefore, as a measure to improve the wear resistance of aluminum alloy materials used in areas where wear resistance is required, surface treatments such as plating, anodizing, or thermal spraying have been applied to create a highly wear-resistant surface treatment layer. Attempts have been made to form a steel sheet, but none of them have yet been able to fully satisfy the requirements for wear resistance. Moreover, in both cases, the adhesion of the surface treatment layer to the base material is insufficient, resulting in the drawback that sufficient durability cannot be ensured when used under high surface pressure.

The object of the present invention is to provide a method for producing an aluminum alloy material with excellent wear resistance, which is characterized by forming a hard alloyed layer in which an Al-based intermetallic compound is crystallized in an Aρ matrix on the surface of the base material. . Another method is to coat the surface of an aluminum or aluminum alloy base material with one or more hard particles supplied from outside the base material, B, Si,

In addition to standard pure aluminum, various aluminum alloys can be used that have the required mechanical properties and processing characteristics depending on the application.
また基材の形状も、適用される部品の形状に応じて任意
に設計すれば良い。Further, the shape of the base material may be arbitrarily designed depending on the shape of the part to which it is applied.

By using such 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.

Further, melting may be carried out on a region where wear resistance is required, but if the region is spread over a wide range, it may be necessary to adjust the oscillation width of a laser beam or the like or sequentially irradiate the region.
基材表面の溶融は基材外部からの金属や硬質粒子の供給

間化合物を形成するものであれば何でも良い。−例とし
てはＮｉ、Ｍｎ。The surface of the base material is melted while metal and hard particles are supplied from outside the base material. Any metal may be used as long as it forms an intermetallic compound with Aρ when melted. - Examples are Ni, Mn.

Each element can be mentioned. Further, it does not necessarily have to be a single metal, but may be supplied in the form of an intermetallic compound, which reacts with Aρ by melting to form an Aρ-based intermetallic compound.
方、硬質粒子としてはＴｉｃ、、ＷＣＳＺｒＣ。On the other hand, the hard particles are Tic, WCSZrC.

その他のセラミックスを挙げうる。これら金属あるいは
硬質粒子は１８のみを用いても良く、あるいは金属どう
し、硬質粒子どうしを２種以上組合せて用いても良い。Examples include carbides such as NbC, nitrides such as TiN5ZrN and CrN, and other ceramics. Only 18 of these metals or hard particles may be used, or two or more metals or hard particles may be used in combination.
また金属と硬質粒子とを組合せても良い。Further, metal and hard particles may be combined.
而して、上記の金属を単に基材とともに溶融した場合、
溶融時に金属の表面張力が大きく、従って濡れ性が悪い
ため基材と反応しにくい。Therefore, when the above metals are simply melted together with the base material,
When melted, the metal has a high surface tension and therefore has poor wettability, making it difficult to react with the base material.
一方、硬質粒子の場合にも基材との濡れ性は良くない。On the other hand, hard particles also have poor wettability with the substrate.

い。この範囲を下回って濡れ性向上元素が少なすぎると
金属あるいは硬質粒子と基材ＡＱとの反応を充分促進で
きないおそれがあり、逆に多すぎると反応促進効果はを
するもののコスト高となるおそれがあるからである。Ge is mutually equivalent in terms of imparting a wettability-improving effect, and it is sufficient to supply at least one of them, but the ratio of metal or hard particles to the total amount of wettability-improving elements is 99:1 by weight. ~70: It is better to specify 30. If the wettability-enhancing element is below this range and there is too little, there is a risk that the reaction between the metal or hard particles and the base material AQ cannot be sufficiently promoted.On the other hand, if it is too high, although the reaction promotion effect will be effective, there is a risk that the cost will increase. Because there is.

粉末塗布法が優れている。One method of supplying the metal, hard particles, and wettability-improving element is to form a mixed powder of these and form a coating layer on the desired site in advance before irradiation with a laser beam or the like. The coating layer is formed by wet plating, C
This can be done by VD, PVD, thermal spraying, etc., or by applying a mixed powder using various binders such as ethyl alcohol. In addition, as another supply mode, there is a case where the mixed powder is directly introduced into the melting zone during irradiation with a laser beam or the like. Although any method may be used, in the case of the direct feeding method, adjustment of the feeding rate, etc. is troublesome, so the coating method, especially the powder coating method using a binder, is superior in terms of simplicity.

l3, Ni2 A, Q3, FeA, Q3, Fe4
AC13, Mn/us, HfAl3, Nb:AC3, C
This results in an alloyed layer in which rA, Q7, etc. are crystallized uniformly and densely or in blocks. On the other hand, in the case of hard particles, an alloyed layer is formed in which the particles are uniformly dispersed or aggregated in an Al matrix. The above intermetallic compounds are generally hard, and the hard particles themselves have excellent hardness, so the alloyed layer as a whole exhibits high hardness and has excellent hardness.

It crystallizes in the l matrix as an Aρ-B intermetallic compound (estimated to be AρB2), Si, and Ge phases, and contributes to improving the hardness of the alloyed layer. The thickness of this alloyed layer can be easily controlled from several tens of micrometers to several millimeters by changing the irradiation conditions of the laser beam, for example, the output, irradiation speed, focus position, etc. Note that the harder the intermetallic compound or hard particles in the Al matrix are, the harder the alloyed layer will be.

Therefore, it can be made suitable as a wear-resistant part required for automobiles and the like. In addition, unlike conventional surface treatment layers such as plating, the alloyed layer is integrally bonded to the base material, so there is no risk of peeling of the wave layer even when used under high surface pressure. , ensuring sufficient durability.

一方、アルミニウム基材単体の硬度を調べたところ、Ｈ
ｖ３０ （荷重５Ｎｇ）であった。On the other hand, when we investigated the hardness of the aluminum base material alone, we found that H
v30 (load 5Ng).
以上の試験結果かられかるように、本発明によれば、極
