【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、金属粉末を焼結させることによるセラミック
スと金属の嵌合方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of fitting ceramics and metal by sintering metal powder.
従来は、特開昭５８−４１７７５号公報に記載されてい
るように，焼結金属が、焼結し、収縮することによる焼
きばめで、金属とセラミックスとを接合していた．
〔発明が解決しようとする課題〕
上記従来技術では、嵌合できるセラミックスの大きさに
限界があった。前述の公知例でも、セラミックスの径は
、たかだか３０＋ｏｍであった。Conventionally, as described in Japanese Patent Application Laid-Open No. 58-41775, metal and ceramics have been joined by a shrink fit in which the sintered metal is sintered and shrinks. [Problems to be Solved by the Invention] In the above-mentioned conventional technology, there is a limit to the size of the ceramic that can be fitted. Even in the above-mentioned known example, the diameter of the ceramic was at most 30+ om.
又、一般の焼きばめ法でも、セラミックスの加工精度が
、非常に厳しく要求される。Furthermore, even in the general shrink fitting method, very strict processing accuracy is required for ceramics.
加工精度が，悪いと、焼きばめ時に、局部的な応力の集
中が生じ、そこが、破壊の起点となる。If machining accuracy is poor, local stress concentration occurs during shrink fitting, which becomes the starting point of fracture.
本発明の目的は、内径がφ６０〜φ１００程度のセラミ
ックスと、金属との嵌合が容易に出来、従来より、セラ
ミックスの加工精度をラフにしても、金属とセラミック
スの嵌合を従来より、容易にすることができる嵌合方法
を提供することにある。The purpose of the present invention is to make it easier to fit metal and ceramics with an inner diameter of about φ60 to φ100, and to make it easier than ever to fit metal and ceramics even if the machining accuracy of ceramics is rougher than before. The object of the present invention is to provide a fitting method that allows for
この目的を達成するため、焼結金属が、圧粉成形体と、
焼結体での寸法変化率がほとんどＯに等しい適正温度（
１０００℃〜１２００℃）で焼或する。To achieve this purpose, the sintered metal is combined into a powder compact and
The appropriate temperature at which the dimensional change rate in the sintered body is almost equal to O (
1000°C to 1200°C).
さらに、大径化を図るためにも，一例として、セラミッ
クスの外部に．ＣＩＰ成形を施すことによって、この目
的は、達或される。Furthermore, in order to increase the diameter, for example, it can be placed on the outside of ceramics. By applying CIP molding, this objective is achieved.
セラミックスと金属は、圧粉成形時の、加圧力により、
基本的には、接合している。Ceramics and metals are compressed by pressure during powder compaction.
Basically, they are joined.
よって，セラミックスの加工精度が、多少ラフでも、本
嵌合は行える。Therefore, even if the machining accuracy of the ceramic is somewhat rough, the final fitting can be performed.
金属粉末を、圧粉体と焼結体とで、ほとんど寸法変化が
０に等しい、焼成温度で、焼或することにより、局所的
な応力集中は起らないので、従来の方法の様に、破壊の
頻度は、極めて少ない。By sintering the metal powder at a sintering temperature where the dimensional change between the green compact and the sintered body is almost zero, local stress concentration does not occur, so unlike conventional methods, The frequency of destruction is extremely low.
以下、本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described below with reference to FIG.
本実施例は、コールドチャンバダイカストマシンのスリ
ーブに、サイアロン２と、ＳＵＳ１のスリーブを、嵌合
させたものである。In this embodiment, Sialon 2 and SUS1 sleeves are fitted into the sleeve of a cold chamber die-casting machine.
外径φ１００〜φ１２０、内径φ７０〜φ８０、長さ３
００〜４００のサイアロンスリーブを焼成し、機械加工
をして外径公差±０．５程度に仕上げる。Outer diameter φ100~φ120, inner diameter φ70~φ80, length 3
00 to 400 Sialon sleeves are fired and machined to an outer diameter tolerance of approximately ±0.5.
次に、本サイアロンセラミックスを，芯金としＳＵＳ粉
末を、ゴム型にパックし、６００〜３０００ｋｇ／一の
静水圧プレスを行ない、サイアロンの外周部に，ＳＵＳ
圧粉成形体を作或する。Next, this Sialon ceramic is used as a core metal, and SUS powder is packed in a rubber mold, and hydrostatic pressing is performed at 600 to 3000 kg/1 to form SUS powder on the outer periphery of the Sialon.
A powder compact is produced.
ついで、この成形体を１１００±２０℃で焼成し、サイ
アロンとＳＵＳを嵌合し、所定の加工を施し、所定の形
状を得た。Next, this molded body was fired at 1100±20° C., SiAlON and SUS were fitted together, and predetermined processing was performed to obtain a predetermined shape.
本発明によれば、種々の金属と、セラミックスの嵌合が
、可能になるため、セラミックスの用途拡大が図れる。According to the present invention, it is possible to fit various metals and ceramics, so that the applications of ceramics can be expanded.
