Title (EN) ALUMINUM DIE-CASTING MOLD PART
(FR) PARTIE DE MOULE DE MOULAGE SOUS PRESSION D'ALUMINIUM
(JA) アルミダイカスト金型用部品
Abstract:
(EN) Provided is an aluminum die-casting mold part having an exposed surface, which is a surface exposed to the cavity of an aluminum die-casting mold, and having a diamond-like carbon coating formed on at least a portion of the exposed surface, wherein the diamond-like carbon coating contains 10-30 at% of hydrogen. The diamond-like carbon coating may further contain less than 10 at% of silicon. Preferably, the content of silicon in the diamond-like carbon coating is 0.5-7 at%. Thereby, an aluminum die-casting mold part having excellent seizure resistance to a molten metal containing aluminum is provided.
(FR) La présente invention concerne une partie de moule de moulage sous pression d'aluminium ayant une surface exposée, qui est une surface exposée à la cavité d'un moule de moulage sous pression d'aluminium, et ayant un revêtement de carbone de type diamant formé sur au moins une partie de la surface exposée, le revêtement de carbone de type diamant contenant de 10 à 30 % atomique d'hydrogène. Le revêtement de carbone de type diamant peut en outre contenir moins de 10 % atomiques de silicium. De préférence, la teneur en silicium dans le revêtement de carbone de type diamant est de 0,5 à 7 % atomiques. Ainsi, l'invention concerne une pièce de moule de moulage sous pression d'aluminium ayant une excellente résistance au grippage vis-à-vis d’un métal fondu contenant de l'aluminium.
(JA) アルミダイカスト金型の空洞部に露出する表面である露出面を有し且つダイヤモンドライクカーボン被膜が露出面の少なくとも一部に形成されたアルミダイカスト金型用部品であって、ダイヤモンドライクカーボン被膜は10at%以上であり且つ30at%以下である含有率にて水素を含む。ダイヤモンドライクカーボン被膜は10at%未満である含有率にて珪素を更に含んでもよい。好ましくは、ダイヤモンドライクカーボン被膜における珪素の含有率は0.5at%以上であり且つ7at%以下である。これにより、アルミニウムを含む溶湯に対する優れた耐焼付き性を有するアルミダイカスト金型用部品を提供する。
