鋳込むことを特徴とした複合材料の製造方法とした。(Means and effects for solving the problem) A method for producing a composite material in which different metals are mixed in the metal, the foamable beads being pre-foamed, and the foaming beads having different metals attached thereto, Fill a model mold with expandable beads prepared by pre-foaming the beads, perform main foaming to produce a vanishing horizontal mold, surround the vanishing model with a molding agent and form a casting opening. This method of manufacturing a composite material is characterized by pouring molten metal into the sewn portion formed by the disappearing model.

６第１図（Ｄ）を製造する０次に鋳造工程を説明する。Polystyrene beads are impregnated with 5% pentane and pre-foamed by steam heating to form beads with a diameter of 1.2 to 2. Cr particles 2 with a diameter of 1 to 2 mm are projected onto the expandable beads 3 of 0 yen to bond the Cr particles 2 and the expandable beads 3 to form bonded beads 3a. Next, the bonding beads 3a are filled into a model forming mold 5 in which the birch-shaped void shown in FIG. After foaming, the disappearing model 6a shown in FIG. 1(B) is manufactured.Next, a void as shown in FIG. 1(C) disappears into the model manufacturing mold 7 in the shape of a claw of a power sillage. Insert the model 6a, fill the other voids with foamable beads 3a, and foam with steam heating to produce the disappearing packet teeth model 6 (FIG. 1(D)) Next, the casting process will be explained. .
消失模型６に塗型を行い第２図に示す様に、消失模型６
を鋳物砂８にて包囲して、押湯９、湯道１０を設けＳＣ
Ｍｎ１Ｈ材の溶湯１１を鋳込する。The vanishing model 6 is painted, and as shown in Fig. 2, the vanishing model 6 is
SC is surrounded by molding sand 8, and a riser 9 and a runner 10 are provided.
A molten metal 11 of Mn1H material is poured.
この様にして製造されたパケットの爪は摩耗し易い先端
部と表面部はＣｒの含有量が高く、高い硬度が得られ、
耐摩耗性の必要でない部分には高価なＣｒを使用しない
ので耐摩耗性の優れたパケットの爪を複合材により得る
ことができた。The claws of the packets manufactured in this way have a high Cr content in the tips and surfaces that are prone to wear, resulting in high hardness.
Since expensive Cr is not used in parts where wear resistance is not required, it was possible to obtain a packet claw with excellent wear resistance using a composite material.
（発明の効果）
本発明によれば異種金属の分布を任意に行うことができ
