Abstract

The present invention relates to a method for preparing aluminum/aluminum nitride or aluminum alloy/aluminum nitride composite materials. Aluminum or an aluminum alloy is melted at a high temperature of 2500°C or higher in a nitrogen (N2) gas atmosphere, in an ammonia (NH3) gas atmosphere, or in an atmosphere of a mixture of the two gases, so as to obtain high-temperature molten aluminum or induce a reaction between a portion of aluminum gas and nitrogen. Preferably, the aluminum or aluminum alloy is melted at the high temperature by arc melting. The method of the present invention involves melting the aluminum or aluminum alloy at a high temperature near a melting point, such that the composite materials may thus be quickly prepared, and aluminum/aluminum nitride or aluminum alloy/aluminum nitride composite materials that can be molded into a panel through cold-rolling may be prepared. In addition, the phase fraction of aluminum nitride may be adjusted by adjusting the arc-melting time, and thus aluminum/aluminum nitride or aluminum alloy/aluminum nitride composite materials having various ratios may be prepared.

11 조약 제 19조 (1 ) 규정의 설 명 서 청구항 보정 내용  11 Description of the provisions of Article 19 (1) of the Treaty Claims Amendment contents

- 청구항 1 및 2: 새로운 청구항으로 교제  - Claims 1 and 2: A new claim

- 청구항 3-5: 원래 출원된 그대로 유지 대제용지에서 청구항 1 은 "알루미늄을 기화하여 반응시키는 인용발명"과 달리 본 발명의 제조과정이 용탕 상태에서 이루어지는 점을 강조할 수 있도록 보정되었으 며, 청구항 2 는 아크 용해에서 아크를 활성화하기 위하여 Ar 가스를 첨가하는 사항 을 추가하여 보정되었습니 다. 본 발명이 용탕 상태에서 반응하는 것은 자명한 사실이 며, Ar 가스를 첨가하여 아크 용해하는 것은 명세서의 15 번 및 32 번 단락 등에 근거하고 있으므로, 국제출원 의 원래 범위를 벗어 나지 않고, 명세서와 도면에 영향을 미치지 않습니 다. 이상에 따르면, 인용발명은 알루미늄을 완전히 기화시켜 질소와 기상 -기상 반응 을 유도함으로써 분말형태의 AIN/AI 나노입자를 제조하는 것이고,  Claim 3-5: In the original application, the claim is corrected to emphasize that the manufacturing process of the present invention is performed in a molten state, unlike in the case of "cited invention in which aluminum is vaporized and reacted" 2 was calibrated by addition of Ar gas to activate the arc in arc melting. It is obvious that the present invention reacts in the molten state. It is based on paragraphs 15 and 32 of the specification that arc melting with the addition of Ar gas is performed. Therefore, without departing from the original scope of the international application, It does not affect According to the above, the reference invention is to produce AIN / AI nanoparticles in powder form by completely vaporizing aluminum to induce a vapor-gas phase reaction with nitrogen,

반면에, 본원발명은 용탕 상태로 반응을 수행하여 액상 -기상 반응을 주로 하되, 알루미늄의 일부만 기화되어 일부의 기상 -기상 반응을 가미한 형태이므로 벌크상태, 즉 용탕이 굳어진 덩어 리 형태로 알루미늄-질화알루미늄 복합재료를 제조할 수 있습 니 다. 그 결고ᅡ, 인용발명은 나노입자를 소결하여 제품을 제조하여야 하는 불편이 있지 만,  On the other hand, the present invention is characterized in that a liquid-gas phase reaction is mainly performed by performing a reaction in a molten state, and since a part of aluminum is vaporized and a part of the vapor-gas phase reaction is added, a bulk state, that is, Aluminum composites can be manufactured. However, there is an inconvenience that a cited invention must manufacture a product by sintering nanoparticles,

본원발명은 소결이 아닌 넁간압연 등의 방법을 적용할 수 있습니 다. 또한, 인용발명은 H2 가스를 사용하여 알루미늄의 기화를 촉진하고, 기화된 알루 미늄과 질소가스가 반응하는 비을을 조절하지 만,  In the present invention, a method such as hot rolling can be applied instead of sintering. The reference also promotes the vaporization of aluminum using H2 gas and controls the rate at which vaporized aluminum and nitrogen gas react,

본원발명은 Ar 가스를 첨가하여 아크 발생을 촉진할 뿐이므로, 알루미늄 용탕이 전부 기화하는 것을 방지할 수 있으며, 그 결과 용탕 상태로 액상 -기상 반응이 이루 어 질 수 있도록 합니 다.  Since the present invention only promotes arc generation by adding Ar gas, it is possible to prevent all of the aluminum molten metal from being vaporized, and as a result, the liquid-gas reaction can be performed in the molten state.
