金属基複合材料部材の製造方法に係る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing a metal matrix composite material member, and more specifically to a metal matrix composite material member in which only a predetermined surface portion is compositely reinforced with a reinforcing material. It pertains to the manufacturing method.

状の複合材料部材を低廉に製造することができる。Problems to be Solved by Prior Art and Inventions One of the methods for producing metal matrix composite materials in which ceramic fibers are used as reinforcement materials and aluminum alloys are used as matrix metals is to place a molded object of the reinforcement material in a mold. A pressure casting method is conventionally known in which a molten matrix metal is introduced into the mold, and the molten matrix metal is solidified while being pressurized within the mold. According to this pressure casting method, composite material members of arbitrary shapes with excellent adhesion between the matrix metal and the reinforcing material can be produced at low cost compared to diffusion bonding methods that require large vacuum generation equipment, etc. can be manufactured.

合強化された複合材料部材を製造するためには、複合強
化されるべき表面部の形状に対応する厚さの小さい所定
の形状の強化材成形体を形成し、鋳造中もその成形体を
鋳型内の所定の位置に保持しなければならない。In order to manufacture a composite material member in which only the surface portion is compositely reinforced with a reinforcing material using such pressure casting method, it is necessary to strengthen a predetermined shape with a small thickness corresponding to the shape of the surface portion to be compositely reinforced. A compact of material must be formed and the compact must be held in place within the mold during casting.

らず、かかる裏面部以外の領域に対し容易に且能率よく
加工を行うことが困難になる。However, because the reinforcing material molded body is small in thickness and is fragile, it is easily damaged during handling, deformed or cracked due to the pressure of the molten metal during casting, and is also easily displaced within the mold. Therefore, it is very difficult to manufacture a composite material member in which only a predetermined surface portion is properly reinforced with a reinforcing material by the conventional pressure casting method. In addition, in order to avoid such problems, it is possible to perform pressure casting using a molded reinforcing material that is much thicker than the surface part that is to be compositely reinforced, but in that case, reinforcement of parts other than the back part Areas that do not need to be strengthened are compositely reinforced with reinforcing materials,
Not only is it difficult to manufacture the composite material member in a low position, but it is also difficult to easily and efficiently process regions other than the back surface portion.

。In addition, Japanese Patent Application Laid-open No. 5
As described in Publication No. 9-23832, a mixture of reinforcing material and a solvent is installed in the mold cavity of the mold,
A method for producing composite material parts is already known, in which a mixture is dried, a molten metal is poured into a mold cavity, and the molten metal is solidified while being pressurized in the mold cavity. The various problems mentioned above in the pressure casting method can be solved and alleviated.
しかしこの方法に於ては、鋳型のモールドキャビティに

あり、またモールドキャビティに多量の強化材を付着さ

囲の大きさが比較的小さい範囲に制限されるという問題
がある。However, in this method, it is difficult to uniformly apply the reinforcing material to the mold cavity of the mold, so it is difficult to uniformly and compositely strengthen the surface part of the component with the reinforcing material. Since it is not possible to attach a large amount of reinforcing material to the steel, there is a problem in that the area that can be compositely strengthened by the reinforcing material is limited to a relatively small area.

表面部のみが強化材にて良好に複合強化された複合材料
部材を容易に且能率よく製造することが困難である。This method also requires the addition of a binder to the solvent in order to deposit a relatively large amount of reinforcing material in the mold cavity, so that the binder remains in the composite region of the manufactured part. The process of applying a large amount of the reinforcing material and solvent mixture to the mold cavity and drying it requires tedious manual work and a long time. Therefore, it is difficult to easily and efficiently manufacture a composite material member in which only a predetermined surface portion is well reinforced with a reinforcing material.

In the former case, it can be avoided that the metal composition of the region other than the composite material differs greatly from the composition of the matrix metal of the composite material. In the latter case, by appropriately selecting the metals constituting the porous molded body, the composition of the constituent metals of the member can be actively changed to a composition different from that of the matrix metal at the same time as composite formation. This allows various properties such as heat resistance and thermal conductivity to be changed.

As a result, this composite material member was also made of an aluminum alloy composite material reinforced with alumina short fibers. The aluminum alloy part has substantially no alumina short fibers, and the Ni content in the aluminum alloy part is lower than the original Ni. It was recognized that the value was higher than the content.
尚何れの複合材料部材に於ても、個々のアルミナ短繊維
の間にアルミニウム合金が良好に充填されており、また
それらの間の密着性も良好であることが認められた。It was also found that in each composite material member, the aluminum alloy was well filled between the individual short alumina fibers, and the adhesion between them was also good.
