Happened. Therefore, in order to investigate the cause, we investigated the relationship between the physical properties of the rotary cooling body and the conditions of collision and separation of droplets.The pure copper rotary cooling body had low hardness and good wettability with metal droplets, and it was gas atomized. When the extremely fine metal powder made by collides with the cooling surface, there is much erosion wear on the surface of the rotating cooling body, and metal droplets are trapped on the uneven surface caused by the wear, and another droplet is deposited on it. It was also found that the detachability of the flat powder due to the centrifugal force deteriorates. Further, in parallel with the occurrence of unevenness due to erosion wear described above, a chemical reaction between the copper and the molten metal droplets on the cooling surface also occurs, and a layer of the reaction product is formed on the cooling surface, resulting in a clean rotary cooling body. I found that I could not keep the surface. Due to these causes, when the powder is produced by the rotary cooling body made of pure copper, there is an unavoidable tendency that the connecting powder increases and the powder becomes coarse. Therefore, it is an object of the present invention to reduce the ratio of the connected powder and the coarse powder contained in the flat powder produced by the above-mentioned apparatus to increase the yield of fine / single (non-connected) powder.

ものである。SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a rotary cooling body is arranged below a nozzle for letting out a molten metal, and before the collision of the molten metal with the rotary cooling body. In a flat powder manufacturing apparatus having a nozzle for injecting gas to form liquid droplets, a ceramic-metal composite mainly composed of ceramics having pores whose porosity does not exceed 5% on the surface of the rotary cooling body. The present invention provides a flat powder manufacturing apparatus, which is characterized in that the film of (1) is formed.

More preferably, it contains 70 to 85% by weight of ceramics. The balance is metal, and heat-resistant metals such as cobalt, nickel and alloys thereof are particularly preferable. When the ceramic composite contains 95% or more of ceramics, it becomes difficult to cover the rotary cooling body, while when the ceramics content is less than 70% by weight, the hardness is low and the surface is often worn. It becomes difficult to keep the surface.

効率が低下するので好ましくない。The base material on which the ceramic composite is applied as a surface coating is preferably copper or copper alloy, aluminum or aluminum alloy, which has excellent thermal conductivity. The thickness of the ceramic composite film is preferably 0.05 μm or more, and the upper limit is not particularly limited, but about 0.2 mm is sufficient. If the thickness is 0.5 mm or more, the cooling efficiency of the rotary cooling body decreases, which is not preferable.

を緩和することができる。Further, in a rotary cooling body coated with a ceramic film having no pores, which is coated by PVD or CVD, when droplets collide with the rotary cooling body, a difference in the coefficient of thermal expansion between the coated non-porous ceramics and the substrate results. Since the non-porous film peels off, a clean surface of the rotary cooling body cannot be obtained, and as a result, the amount of droplets adhering to the surface of the rotary cooling body and the amount of connecting powder increase, resulting in a flat powder with a small particle size yield. become worse. That is, by coating the surface of the rotary cooling body with ceramics in which fine pores are dispersed by a method such as plasma spraying, it is possible to reduce the surface roughness of the rotary cooling body after droplet collision, and at the same time, to reduce the ceramic composite and the base material. The adverse effect due to the difference in thermal expansion from the material can be mitigated.

体の気孔率は５％以下でなければならない。The porosity of the ceramic composite to be coated is 5
If it exceeds%, the surface roughness of the rotary cooling body becomes large because the pores become coarse. Then, since the metal of the base material exposed in the pores reacts with the molten metal, a clean surface of the rotary cooling body cannot be obtained. Therefore, the yield of the flat powder having a small particle diameter is deteriorated. Therefore, the porosity of the ceramic composite should be 5% or less.

れに対して本発明実施例は微細扁平粉末の収率が高い。As can be seen from the above results, when the porosity of the ceramic composite coating is zero (in the case of PVD coating), droplets adhere to the coating and peeling occurs. Further, the yield of fine flat powder is very low, which is lower than that of the conventional example using the rotary cooling body without the ceramic composite coating. Further, when the porosity of the ceramic composite coating is more than 10% or more, the liquid droplets locally adhere to the rotary cooling body, and the yield of the flat fine powder decreases accordingly. On the other hand, in the examples of the present invention, the yield of fine flat powder is high.
