COMPOSITE BODY OF ALUMINUM-GRAPHITE-CARBIDE
PROBLEM TO BE SOLVED: To provide a composite body that improves brittleness of the composite body and has preferable thermal conductivity, and a method for producing the composite body.SOLUTION: There is provided a composite body of aluminum-graphite-carbide which produces through the following steps. The steps include: mixing coke powder or mixed powder of the coke powder and graphite powder, and any one of carbide powder, oxide powder, and metal powder; forming a paste-like substance by adding tar or pitch to the mixed powder obtained in the above step to extrude and mold it, and then conducting primary firing that fires it at 1,000 to 1,500°C to obtain a solid; repeating a step of impregnating the solid obtained in above step with tar or pitch, and conducting primary firing that fires it at 1,000 to 1,500°C to obtain the solid, several times to conduct final firing that fires it at 2,500 to 3,000°C to obtain an extrusion molding body; and impregnating under pressure the extrusion molding body obtained by above final firing with aluminum or aluminum alloy by using a melt forging method.SELECTED DRAWING: None
【課題】複合体の脆弱性を改善し、且つ、好適な熱伝導度を有する複合体と、その製造方法を提供する。【解決手段】次の工程を経て製造されるアルミニウム−黒鉛−炭化物複合体。コークス粉末、又は、コークス粉末と黒鉛粉末との混合粉末と、炭化物粉末、酸化物粉末、金属粉粉末の何れかとを混合する工程、前記工程で得た混合粉にタール又はピッチを加えてペースト状の物質を作り、これを押出成形し、その後１，０００〜１，５００℃にて焼成する一次焼成で固形物を得る工程、前記工程で得た固形物に対してタール又はピッチを含浸して１，０００〜１，５００℃で焼成する一次焼成により固形物を得る工程を複数回繰り返し、２，５００〜３，０００℃で焼成する最終焼成により押出成形体を得る工程、前記最終焼成により得た押出成形体に対して熔湯鍛造法によりアルミニウム又はアルミニウム合金を加圧含浸させる工程。【選択図】なし
