しかじな、がら、ＡＩ！、合金は、一般に耐摩耗性の点
で鉄系材料に劣るためその普及が伸び悩んでいる。Yes, it's AI! , alloys are generally inferior to iron-based materials in terms of wear resistance, so their popularity has slowed.
そこで、従来、Ａ１合金材料の耐摩耗性を向上させるた
めに、これが要求される部位に陽極酸化処理や溶射処理
を施し３表面層を形成する方法が提案されている。Therefore, in order to improve the wear resistance of the A1 alloy material, a method has been proposed in which three surface layers are formed by applying anodization treatment or thermal spraying treatment to the areas where this is required.

A method of forming an overlay alloy layer of r) and A2 on the surface has been proposed (Japanese Patent Application Laid-Open No. 61-166982.
66984).
しかし、これらの技術は、肉盛金属の硬さ、耐摩耗性の
面では良いが、肉盛金属層に割れや剥離。However, although these techniques are good in terms of the hardness and wear resistance of the overlay metal, they can cause cracking and peeling of the overlay metal layer.

を特徴とするアルミニウム合金材料の肉盛溶接方法にあ
る。(Means for Solving Problems) The present invention provides overlay material on the surface of the aluminum alloy material and irradiates the overlay material with high-density energy such as a laser beam. In the method for forming a metal layer, the overlay welding method for an aluminum alloy material is characterized in that the overlay material contains 30% or more of silicon.

とが好ましい。Wrinkles often occur in the build-up area, and cracks and peeling also occur. In addition, when it is 30% or more, these problems do not occur, the adhesion is good, and the finished state is also beautiful. However, as the amount of silicon increases, the hardness of the overlay metal decreases (Figure 1). Therefore, in order to maintain the hardness at about Hv500 or higher, the amount of silicon is preferably 30 to 50%.
