Description
본 발명은 불활성 가스 분위기 하에서 용융 미립화한 분말을 이용하여 경질 재료가 포함되어 있는 알루미늄 또는 Al-합금, 특히 MMC(금속 매트릭스-복합재료)로부터 부품을 제조하기 위한 방법 및 상기 방법에 따라 제조된 부품 또는 반제품에 관한 것이다.The present invention relates to a method for producing a component from aluminum or an Al-alloy, particularly MMC (metal matrix-composite material) containing a hard material by using a melt-atomized powder in an inert gas atmosphere, and a component Or semi-finished products.
분무 압축법에 의해 알루미늄(Al) 또는 Al-합금과 같은 금속으로부터 부품을 제조하는 것이 알려져 있다. 분무 압축법에서는 불활성 가스 분위기(예를 들면 질소)에서 용융물을 미립화하여 타깃에 증착시킨다. 상기 방법은 냉각속도가 매우 높고 과공정(hypereutectic) 합금을 제조할 수 있다는 장점이 있다. 이러한 방법은 예를 들면 EP 0198613, EP 0200349, EP 0574458과 EP 0517882에 기재되어 있다.It is known to manufacture parts from metals such as aluminum (Al) or Al-alloys by spray compression. In the spray compression method, the melt is atomized in an inert gas atmosphere (for example, nitrogen) and deposited on a target. The process has the advantage that the cooling rate is very high and hypereutectic alloys can be produced. Such methods are described, for example, in EP 0198613, EP 0200349, EP 0574458 and EP 0517882.
상기 방법에서는 MMC-반제품을 제조하기 위해 SiC, B4C 또는 Al2O3와 같은 세라믹 입자를 부가하여 보강하는 것이 또한 알려져 있다. 이렇게 제조된 구조체에는 성분(예를 들면 SiC와 Al)의 입자가 치밀하게 결합되어 존재한다. It is also known in the method that ceramic particles such as SiC, B 4 C or Al 2 O 3 are added and reinforced to produce MMC semi-finished products. Particles of components (for example, SiC and Al) are tightly coupled to the thus-prepared structure.
상기 방법에서는 반제품 이외에 소위 과분무(overspray)가 발생하여 공정에 재투입하거나 부산물로서 재처리할 수 있다.In this method, a so-called overspray occurs in addition to the semi-finished product and can be re-introduced into the process or reprocessed as a by-product.
주조품의 주조 중에 액상 Al-용융물에 MMC-입자를 혼입하기도 한다(듀랄캔(Duralcan) 공정).MMC-particles may also be incorporated into the liquid Al-melt during casting of the casting (Duralcan process).
마찬가지로 알려져 있는 SPS(스파크-플라즈마-소결)-공정에서는 분말 또는 분말 혼합물을 압축함으로써 소정의 용도를 위해 제조된 공작물 또는 반제품 내 입자의 조직 밀도를 가장 알맞게 최적화한다.In a similarly known SPS (spark-plasma-sintering) - process, the texture density of the particles in the workpiece or semi-finished product prepared for a given application is optimized optimally by compressing the powder or powder mixture.
상기 종래기술(분말 혼합법)의 단점 중 하나는 보강 입자와 매트릭스 간의 결합이 충분하지 않다는 것이고, 또 다른 단점은 혼합물의 균질성이 충분히 확보되지 않는다는 점이다. 상기 2개의 단점은 혼합에 의해 제조한 부품, 예를 들면 브레이크 디스크의 기계적 내응력성에 나쁜 영향을 미친다. 이와 관련하여, 공정과 관련된 잔류 기공도를 억제하고 안정적인 특성값을 설정하여 안정적인 기계적 특성값으로 조절하기 위한 후속 압밀화 공정(예를 들면 압연, 단조 또는 압출)이 추가로 필요하게 된다.One of the disadvantages of the prior art (powder mixing method) is that the bonding between the reinforcing particles and the matrix is not sufficient, and another disadvantage is that the homogeneity of the mixture is not sufficiently secured. The above two disadvantages have a bad influence on the mechanical stress resistance of a component manufactured by mixing, for example, a brake disc. In this regard, there is a further need for a subsequent consolidation process (e. G., Rolling, forging or extruding) to control the residual porosity associated with the process and to set stable characteristic values to provide stable mechanical properties.
이에 따라, 본 발명의 과제는 보강 입자가 용융 미립화 공정에 의해 생성된 구상의 분말입자에 견고하면서 균질하게 결합되어 있고 후속 압밀화 공정(예를 들면 압연, 단조 또는 압출)을 필요로 하지 않는 부품 또는 반제품 제조 방법을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a method for manufacturing a powder compact, in which the reinforcing particles are firmly and homogeneously bonded to the spherical powder particles produced by the melt atomization process and which do not require a subsequent consolidation process (for example, rolling, forging or extruding) Or semi-finished products.
본 발명에 따르면, 상기 과제는 분무 공정 중에 또는 분무 공정의 후속 공정 중에 용융 미립화한 금속, 특히 알루미늄 또는 알루미늄 합금에 보강-입자를 부가함으로써 해결된다.According to the invention, this object is solved by adding reinforcement-particles to the melt-atomized metal, in particular aluminum or aluminum alloy, during the spraying process or in a subsequent process of the spraying process.
도 1은 부품 단면에서 응력 방향으로 분포된 MMC-함량 조성도이다.
도 2는 응력 방향으로 지지부 위에 MMC-분말이 SPS-공정에 의해 도포되어 기능층이 형성되어 있는 구배도이다.1 is a MMC-content composition diagram distributed in the direction of stress in the cross section of the component.
Fig. 2 is a gradient in which MMC powder is applied on the support in the stress direction by the SPS process to form a functional layer.
미립화 공정 중에 보강-입자가 견고하면서 균질하게 결합되어 있는 금속-(특히 Al-) MMC-분말 입자가 생성된다.During the atomization process, metal- (especially Al-) MMC-powder particles are formed which are firmly and homogeneously bonded with reinforcement-particles.
MMC-입자를 후속 부가하는 변형예에서는 체로 거른 후 용융 미립화 공정에 의해 미리 제조한 알루미늄 또는 알루미늄 합금 분말에 MMC-입자를 부가하여 균질하게 혼합한다. In the modification example in which the MMC particles are subsequently added, the MMC particles are added to the aluminum or aluminum alloy powder previously prepared by sieving and then homogeneously mixed by the melt atomization process.
모든 변형예에서는, 이어서 상기 분말 입자를 SPS-공정에 의해 압축하여 부품 또는 반제품을 제조한다.In all variations, the powder particles are then compressed by the SPS-process to produce the part or semi-finished product.
상기 압축에 의해 생산된 부품에는 MMC-경질 재료가 매우 균일하게 분포되는데, 이는 부품 또는 반제품의 조직 구조와 기계적 특성에 실질적으로 긍정적인 영향을 준다.The parts produced by this compression have a very uniform distribution of the MMC-hard material, which has a substantially positive impact on the tissue structure and mechanical properties of the part or semi-finished product.
본 발명에 따르면, 부품 또는 반제품은 미립화 공정 후 실시되어 높은 조직 밀도(동시에 매우 작은 입도)를 가능하게 하는 SPS-공정에 의해 보강된다. 제조된 부품 또는 반제품의 추가 압밀화 공정(예를 들면 압연, 주조 또는 압출)은 더 이상 필요하지 않게 된다.According to the present invention, the part or semi-finished product is reinforced by the SPS process, which is carried out after the atomization process to enable high tissue density (and very small particle size) at the same time. Further compaction processes (e.g. rolling, casting or extruding) of the manufactured parts or semi-finished products are no longer necessary.
과분무로부터 생성된 금속 입자를 이용하는 경우에는 상기 금속 입자를 보강 입자와 혼합하기 전에 체거름에 의해 입자 범위를 < 250 ㎛까지 조절한다. In the case of using the metal particles produced from the excess powder, the particle range is adjusted to <250 μm by sieving before the metal particles are mixed with the reinforcing particles.
보강-입자가 부가된 상술한 금속-, 경우에 따라 알루미늄 또는 알루미늄 합금은 예를 들면 규소 함량이 5 내지 25 중량-퍼센트이고, 철 함량이 2 내지 10 중량-퍼센트이고, 니켈 함량이 2 내지 5 중량-퍼센트이고, 망간 함량이 0 내지 3 중량-퍼센트이고, 마그네슘 함량이 0 내지 1 중량-퍼센트이고, 잔량이 알루미늄인 과공정 알루미늄 합금으로 구성된다.The reinforcing-particulate-added above-described metal, if appropriate aluminum or aluminum alloys, may for example have a silicon content of from 5 to 25 percent by weight, an iron content of from 2 to 10 percent by weight, a nickel content of from 2 to 5 By weight, a manganese content of 0 to 3% by weight, a magnesium content of 0 to 1% by weight, and a balance aluminum.
사용된 MMC 또는 경질 재료 입자의 크기는 1 내지 50 ㎛인 것이 유리하다. SPS 공정에서 추가 가공하기 위해 상술한 방법에 의해 제조된 250 ㎛ 이하의 크기를 가진 MMC-분말 입자를 사용한다.The size of the MMC or hard material particles used is advantageously between 1 and 50 mu m. MMC powder particles having a size of 250 mu m or less manufactured by the above-described method for further processing in the SPS process are used.
본 발명은 상술한 바와 같은 방법 및 상기 방법에 의해 최종 크기에 가깝게 제조되고 특히 높은 기계적 응력 및/또는 열적 응력에 내성이 큰 부품 또는 반제품에 관한 것이다. 이러한 부품은 예를 들면 본 발명에 따른 방법에 의해 제조될 수 있는 자동차용 브레이크 디스크 또는 마찰 링인 것이 바람직하다. 이러한 브레이크 디스크 또는 마찰 링은 모노 디스크, 봉입기 또는 슬라이더에 의해 제조된 통기성 디스크 또는 멀티-파트 통기성 디스크일 수 있다.The present invention relates to a component or semi-finished product which is manufactured to a final size and which is particularly resistant to high mechanical stresses and / or thermal stresses as described above and by the method. Such parts are preferably brake discs or friction rings for automobiles, which can be produced, for example, by the method according to the invention. Such brake discs or friction rings may be breathable discs or multi-part breathable discs made by means of monodispersions, barbs or sliders.
또한 이러한 브레이크 디스크 또는 마찰 링은 응력에 상응하게 축 방향 및/또는 반경 방향으로 조직 구성이 분포될 수 있는데, 즉 도 1에 도시되어 있는 바와 같이 제조 중에 MMC-함량과 관련한 조성이 부품 단면에서 응력 방향으로 분포될 수 있다.In addition, these brake discs or friction rings can be distributed in the axial and / or radial directions of the structure corresponding to the stresses, that is to say that the composition in relation to the MMC-content during manufacture, as shown in Figure 1, Lt; / RTI >
또한 도 2에 도시되어 있는 바와 같이, 응력 방향으로 지지부로서 균일한 본체 위에 MMC-분말을 SPS-공정에 의해 추가 도포하여 기능층을 형성하는 구배를 얻을 수 있다.Also as shown in Fig. 2, a gradient can be obtained in which the MMC-powder is further applied by a SPS-process on the uniform body as the support in the stress direction to form the functional layer.
