Abstract: front page image
(EN)According to the present invention, disclosed is an aluminium alloy composition used in the formation of a local strengthening layer by means of build-up welding in a local position where abrasion resistance and durability are required in an aluminium piston (10); being an aluminium alloy composition for local strengthening of an aluminium piston wherein carbon nanotubes (CNT) are added in an amount of between 1 and 5 wt.% or graphene is added in an amount of between 1 and 5 wt.% to an aluminium alloy of which the main component is aluminium (Al) and which has a silicon content comprising any one of: a silicon (Si) content of between 5 and 8 wt.%, a silicon (Si) content of between 10 and 13 wt.%, or a silicon (Si) content of between 15 and 19 wt.%.
(FR)La présente invention concerne une composition d'alliage d'aluminium utilisée pour la formation dans un piston en aluminium (10) d'une couche de renforcement local au moyen d'un soudage de rechargement dans une position locale au niveau de laquelle une résistance à l'abrasion et une durabilité sont nécessaires. Ladite composition d'alliage d'aluminium permet un renforcement local d'un piston en aluminium dans lequel des nanotubes de carbone (CNT) sont ajoutés en une quantité représentant de 1 à 5 % en poids, ou du graphène est ajouté en une quantité représentant de 1 à 5 % en poids, à un alliage d'aluminium dont le principal composant est l'aluminium (Al) et dont la teneur en silicium (Si) représente de 5 à 8, de 10 à 13 ou de 15 à 19 % en poids.
(KO)본 발명에 따르면, 알루미늄 피스톤(10)의 내마모성 및 내구성이 요구되는 국부적인 위치에 육성용접되어 국부강화층을 형성하는데 이용되는 알루미늄합금 조성물에 있어서, 알루미늄(Al)을 주성분으로 하되, 5 내지 8중량%의 규소(Si) 함량 또는, 10 내지 13중량%의 규소(Si) 함량 또는, 15 내지 19중량%의 규소(Si) 함량 중 어느 하나의 규소(Si) 함량을 갖는 알루미늄합금에, 1 내지 5중량%의 카본나노튜브(CNT) 또는 1 내지 5중량%의 그래핀(Graphene)이 첨가된 알루미늄 피스톤의 국부강화용 알루미늄합금 조성물을 개시한다.
