As shown in b), alloy powder 2 such as A1 (see Fig. 2 (a)) is sintered on Mg powder compacted densely by compaction, and when Mg and Aβ are alloyed, the alloy powder A Mg-Aβ or Mg-Zn eutectic reaction occurs where the elements are not yet uniformly diffused and are concentrated, and the eutectic melt becomes Mg.
A eutectic outflow hole is formed by flowing out from around the Mg-A2 alloy particle 3, and a diameter of 20 to 50μ is created around the Mg-A2 alloy particle 3.
The coarse bore 4 (see FIG. 2(b)) of 1.5 m remained and had an adverse effect on the mechanical strength and surface treatment of the sintered product. On the other hand, when alloy powder is used as a raw material, the powder is solid solution strengthened and becomes hard, and the hardness is more than twice that of a single element (Hv = 80 or more), as shown in Figure 3 ( a),
Shown in (b)! As shown, even when molded using a normal die press, considerable bores remained in the gaps between the alloy powder particles 3 (see Figure 3 (b)), and sufficient density could not be obtained, and the density after sintering was also low. (See Section 3(b)).

A method for producing a magnesium-based sintered alloy is provided.
以下、本発明の構成要件を説明する。Hereinafter, the constituent elements of the present invention will be explained.

One or more types of i.
また合金元素の含有量も特に制限はなく、一般に合計量

００〜６５０℃、０．５〜８時間、Ａｒ雰囲気で行う。Powder metallurgy conditions for compacting and sintering the raw material powder are also known. Typically, the powder is compacted using a die press at a pressure of 0.5 to 8 ton/am" and then sintered. The result is 5
It is carried out at 00 to 650°C for 0.5 to 8 hours in an Ar atmosphere.

グし、得られた粉末を混合し、以下圧粉・焼結を行う。In the raw material preparation method that is the most distinctive feature of the present invention, Al1 and Zri, which are alloying elements, are added to the surface of the Mg particles that are the raw material.
The powder is coated by sputtering, vapor deposition, electroless plating, etc., and the resulting powder is mixed, followed by compaction and sintering.

50 to -325 mesh. The coating thickness of the alloying element is adjusted to the desired amount of alloying element, with typical coating thicknesses ranging from 0.1 to 10 ILm.

使用してもよい。Since it is difficult to apply a uniform film with a thin coating film thickness of 0.1 μm or less, a coating film thickness of 0.1 μm or more is preferable. In this case, when the amount of alloying elements in the magnesium-based alloy is small, if only coated magnesium powder is used, the alloying element content will be too large.
Uncoated (pure) magnesium powder may also be used in combination.

The method is characterized in that one or more types selected from Q*Os) particles are mixed, the resulting mixed powder is compacted, and then sintered. These boron and other particles are added as a hard secondary dispersed phase to the magnesium alloy mainly to improve the wear resistance and Young's modulus.

好ましい。また添加物質の粒度は１μｍ以下の平均粒径
のものが好ましい。The amount added depends on the application and usage conditions and is not particularly limited, but in general, if it exceeds 30% by volume, it becomes difficult to compress the powder and the density of the green compact decreases, so it is preferably 30% by volume or less. Further, the particle size of the additive substance is preferably one having an average particle size of 1 μm or less.

Since it is widely dispersed around the pure magnesium powder particles, the outflow pores of the eutectic liquid are also small, and the coarse bores are also reduced.

９０％の高い圧粉体密度が得られる。FIGS. 1(a) and 1(b) are drawings conceptually explaining the powder compaction and sintering steps in the method of the present invention. When the Mg powder 1 with the Aβ coating attached is pressed in the direction of the arrow by a die press, the powder itself is deformed while the bore 4 is crushed (see FIG. 1(a)). As a result, the true density ratio is 80~
A high green compact density of 90% can be obtained.

A part of 2 enters the eutectic liquid and flows out, but most of it diffuses into the Mg powder 1 to obtain alloy powder particles 3. The bore 4 in the sintered product is composed of what was present in the powder compact and eutectic outflow holes (see FIG. 1(b)).
また、焼結品中のボア４は主として共晶流出孔の発生に
起因して生ずる。この結果、真密度比で８５〜９５％の
密度の焼結体が得られる。Further, the bores 4 in the sintered product are mainly caused by the occurrence of eutectic outflow holes. As a result, a sintered body having a density of 85 to 95% in terms of true density ratio is obtained.

固に保持しある程度防止することができる。In addition, since substances such as boron and alumina do not significantly diffuse with Mg unlike alloying elements such as Al1, the problem of deterioration of sintering properties mentioned in connection with alloying elements does not occur. It tends to fall off easily during sliding. This tendency can be alleviated by increasing the density of the sintered body.
This can be prevented to some extent by firmly holding alumina etc. with a magnesium alloy matrix.
