티탄늄-알루미늄 분말 합금 제조방법Titanium-aluminum powder alloy manufacturing method

본 발명은 티탄늄-알루미늄 분말 합금을 제조하는 방법에 관한 것으로서, 특히, 티탄늄 용융물과 알루미늄 용융물을 자기장내에 개별 분사하여 교반시키는 방식의 제조방법을 제공함으로써, 상온에서도 티탄늄-알루미늄 분말 합금을 제조할 수 있게 한 티탄늄-알루미늄 분말 합금 제조방법에 관한 것이다.The present invention relates to a method for producing a titanium-aluminum powder alloy, and in particular, by providing a method of manufacturing a method in which the titanium melt and aluminum melt are separately sprayed and stirred in a magnetic field, thereby providing a titanium-aluminum powder alloy at room temperature. The present invention relates to a method for producing a titanium-aluminum powder alloy which can be produced.

일반적으로 티탄늄-알루미늄 분말 합금은 가벼울 뿐만 아니라 기계적 성질이 우수하여 소결 합금용으로 많이 이용되는 추세이다.Generally, titanium-aluminum powder alloys are not only light but also have excellent mechanical properties, and thus are widely used for sintered alloys.

이러한 티탄늄-알루미늄 분말 합금은 티탄늄과 알루미늄을 고온 하에서 함께 용융시킨 후, 분말 상태로 성형하는 방법으로 제조된다.This titanium-aluminum powder alloy is manufactured by melting titanium and aluminum together under high temperature and then molding the powder into a powder state.

그러나, 이와 같은 기존의 제조방법에서는 티탄늄과 알루미늄을 함께 용융시키기 위해서는 티탄늄의 융점 예를 들면, 1800℃ 보다 더 높은 온도를 필요로 하기 때문에 상당한 비용이 소요될 뿐만 아니라 조직 상태도 균일하지 못한 단점이 있었다.However, such a conventional manufacturing method requires a melting point of titanium, for example, a temperature higher than 1800 ° C. in order to melt the titanium and aluminum together. There was this.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 티탄늄 용융물과 알루미늄 용융물을 각각 용융시킨 다음, 이것들을 자기장내에 개별 분사하여 교반시키는 동시에 냉각수단을 이용하여 분말 상태로 성형하는 방식의 제조방법을 제공함으로써, 비교적 낮은 온도에서도 티탄늄-알루미늄 분말 합금을 제조할 수 있으며, 균일한 조직 상태를 갖는 티탄늄-알루미늄 분말 합금을 얻을 수 있게 하는데 그 안출의 목적이 있는 것이다.Accordingly, the present invention has been made in view of the above, and the method of melting the titanium melt and the aluminum melt, respectively, and then separately spraying them in a magnetic field and agitating them to form a powder using cooling means. By providing a method, it is possible to produce titanium-aluminum powder alloys at relatively low temperatures, and to provide a titanium-aluminum powder alloy having a uniform structure state.

이하, 첨부도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 티탄늄과 알루미늄을 각각 용융시킨 다음, 각각의 용융물을 양편의 전자석 사이에 형성되어 있는 자기장내에 개별 분사하여 이것들이 자기작용에 의해 교반되게 하고, 교반된 용융물들이 일정한 무게를 갖게 되면 낙하되어 냉각수단을 거치면서 분말 상태로 수집할 수 있게 하는 방법으로 제조하는 것을 특징으로 한다.The present invention melts titanium and aluminum, respectively, and then individually melts each melt into a magnetic field formed between the electromagnets on both sides so that they are stirred by magnetic action, and when the stirred melts have a constant weight, they fall. It is characterized in that it is manufactured by a method that can be collected in a powder state while passing through the cooling means.

특히, 상기 티탄늄과 알루미늄 용융물들이 교반되는 주위는 진공 챔버로 밀폐되어 있는 것을 특징으로 한다.In particular, the surroundings in which the titanium and aluminum melts are stirred are sealed by a vacuum chamber.

이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

첨부한 도 1을 참조하여 본 발명의 티탄늄-알루미늄 분말 합금 제조방법을 살펴보면 다음과 같다.Looking at the titanium-aluminum powder alloy manufacturing method of the present invention with reference to the accompanying Figure 1 as follows.

먼저, 티탄늄과 알루미늄을 각각의 융점온도 예를 들면, 약 1800℃ 와 600℃ 로 용융시킨다.First, titanium and aluminum are melted at respective melting point temperatures, for example, about 1800 ° C and 600 ° C.

이렇게 용융시킨 티탄늄과 알루미늄의 각 용융물을 미세한 입자 상태로 상호 일정간격을 두고 배치되는 양편의 전자석(10) 사이에 함께 분사한다.The molten titanium and aluminum melted in this way are sprayed together between the electromagnets 10 on both sides arranged at a predetermined interval from each other in a fine particle state.

이때, 전자석(10) 사이에는 자기장이 형성되게 되고, 미세한 입자 상태로 분사되는 티탄늄과 알루미늄의 각 입자들은 자성을 띄게 되므로서, 분사된 입자들은 자기장내에서 불규칙적으로 유동 및 충돌하게 되고, 이와 동시에 함께 섞이면서 입자 간의 개별적인 융착이 진행될 수 있게 된다.At this time, a magnetic field is formed between the electromagnets 10, and each of the particles of titanium and aluminum sprayed in a fine particle state becomes magnetic, so that the sprayed particles flow and collide irregularly in the magnetic field. At the same time, the individual fusion between the particles can proceed as they are mixed together.

이때, 입자들이 교반되는 자기장 주위는 진공 챔버(11)에 의해 밀폐되어 있어 불순물이 혼합되는 것을 막을 수 있게 된다.At this time, the magnetic field around which the particles are stirred is sealed by the vacuum chamber 11 to prevent the impurities from being mixed.

이렇게 교반되어 미세 단위로 융착된 구형상의 티탄늄-알루미늄 입자들은 일정한 자체 무게를 갖게 되면, 자기장 영역의 아래쪽으로 연장되어 있는 슈트(12)를 따라 낙하하게 되고, 계속해서 슈트(12)의 하단 주위에 배치되어 있는 냉각 유니트(13)를 거치면서 분말 상태로 용기(14)내에 수집될 수 있게 된다.The spherical titanium-aluminum particles thus agitated finely and uniformly have a constant self weight, and fall along the chute 12 extending below the magnetic field region, and continue around the bottom of the chute 12. It can be collected in the container 14 in a powder state while passing through the cooling unit 13 disposed in the.

따라서, 본 발명의 티탄늄-알루미늄 분말 합금 제조방법에서는 티탄늄과 알루미늄을 각각 별도로 용융시키게 되므로 기존과 같이 고온의 용융조건을 필요로 하지 않게 되며, 즉 본 발명의 제조과정 특히, 교반과정이 대부분 상온에서 이루어지게 되므로 제조시 소요되는 비용을 상당히 절감할 수 있게 되며, 진공 상태의 주변조건 하에서 자기작용을 이용하여 각각의 용융물을 교반시키게 되므로 합금 분말의 조직 상태를 안정상(狀)으로 균일하게 유지할 수 있게 된다.Therefore, in the titanium-aluminum powder alloy manufacturing method of the present invention, since the titanium and aluminum are separately melted, high temperature melting conditions are not required as in the prior art, that is, the manufacturing process of the present invention, in particular, the stirring process is mostly performed. Since it is made at room temperature, the cost of manufacturing can be considerably reduced, and each melt is agitated by magnetic action under ambient conditions in a vacuum state, so that the state of alloy powder is uniformly stabilized. It can be maintained.

이상에서와 같이 본 발명은 티탄늄과 알루미늄의 각 용융물을 자기장내에서 교반시키는 방법을 이용하여 티탄늄-알루미늄 분말 합금을 상온 제조할 수 있게 함으로써, 제조비용 절감의 효과를 도모할 수 있으며, 고 품질의 분말 합금을 얻을 수 있는 장점이 있는 것이다.As described above, the present invention enables the production of titanium-aluminum powder alloy at room temperature using a method of stirring each melt of titanium and aluminum in a magnetic field, thereby reducing the manufacturing cost, There is an advantage to obtain a quality powder alloy.
