Zusammenfassung: | The present invention relates to an amorphous alloy having low frictional resistance and capable of improving abrasion resistance, a target made of the amorphous alloy, and a compressor comprising a layer of the amorphous alloy as a coating layer. According to the present invention, it is possible to secure high hardness and a low elastic modulus of the coating layer by controlling a microstructure having an amorphous phase as a primary phase by using Ti-based three-component to five-component amorphous alloys. As a result, it is possible to prevent the coating layer from being peeled off from a matrix or destroyed, and thus it is possible to achieve the effect of improving reliability or durability of a mechanical apparatus such as a compressor.
La présente invention concerne un alliage amorphe présentant une faible résistance au frottement et pouvant améliorer la résistance à l'abrasion, une cible constituée de l'alliage amorphe, et un compresseur comprenant une couche de l'alliage amorphe comme couche de revêtement. Selon la présente invention, il est possible de garantir une dureté élevée et un faible module d'élasticité de la couche de revêtement par régulation d'une microstructure présentant une phase amorphe comme phase primaire en utilisant des alliages amorphes contenant de trois à 5 composants à base de Ti . Par conséquent, il est possible d'empêcher le décollement ou l'élimination de la couche de revêtement d'une matrice, et d'obtenir ainsi l'effet d'une meilleure fiabilité ou durabilité d'un appareil mécanique tel qu'un compresseur.
본 발명은 마찰 저항이 작고 내마모성을 개선할 수 있는 비정질 합금과 상기 비정질 합금으로 이루어진 타겟, 그리고 상기 합금층을 코팅층으로 포함한 압축기에 관한 것이다. 본 발명에 따르면, Ti계 3원계 내지 5원계 비정질 합금을 이용하여 비정질을 주상으로 하는 미세조직을 제어함으로써 코팅층의 높은 경도와 낮은 탄성계수를 확보할 수 있다. 그 결과 코팅층이 기지로부터 박리되거나 파괴되는 것을 억제할 수 있어 압축기와 같은 기계 장치의 신뢰성 또는 내구성을 향상시킬 수 있는 효과를 가지게 된다. |
