Title (EN) ANTIBACTERIAL MEMBER
(FR) ÉLÉMENT ANTIBACTÉRIEN
(JA) 抗菌性部材
Abstract:
(EN) Provided is an antibacterial member capable of maintaining a high antibacterial effect and excellent osteoconductive properties over a long period of time. The antibacterial member according to the present invention, which is provided with a fluorine-containing DLC film (F-DLC film) 40 on at least a part or the entire of the outermost surface of a base material 10, is characterized in that the element ratio (F/F+C) of the F-DLC film is 17-72% and the nanoindentation hardness is 2,000-16,000 MPa. Thus, an antibacterial member capable of sustaining a high wear resistance and good adhesion and maintaining a high antibacterial effect and excellent osteoconductive properties over a long period of time can be obtained. The F-DLC film does not necessarily cover the entire outermost surface of the base material but may be disposed in spots thereon.
(FR) La présente invention concerne un élément antibactérien permettant de maintenir un effet antibactérien élevé et d'excellentes propriétés ostéoconductrices sur une longue durée. L'élément antibactérien selon la présente invention, qui est doté d'un film de DLC (carbone sous forme de diamant amorphe) contenant du fluor (film de F-DLC) 40 sur au moins une partie ou la totalité de la surface la plus externe d'un matériau de base 10, est caractérisé en ce que le rapport des éléments (F/F+C) du film de F-DLC est de 17 à 72 % et en ce que la dureté de nanoindentation est de 2 000 à 16 000 MPa. Ainsi, un élément antibactérien permettant de conserver une résistance élevée à l'usure et une bonne adhérence et de maintenir un effet antibactérien élevé et d'excellentes propriétés ostéoconductrices sur une longue durée peut être obtenu. Le film de F-DLC ne recouvre pas nécessairement toute la surface la plus externe du matériau de base mais peut être disposé en des points sur celui-ci.
(JA) 高い抗菌性と高い骨伝導性を長期間維持できる抗菌性部材を提供する。 本発明の抗菌性部材は、基材10の最表面の少なくとも一部又は全体にフッ素を含むDLC膜(F-DLC膜)40を備えており、前記F-DLC膜の元素比(F/F+C)が17%~72%、且つナノインデンテーション硬さが2,000MPa~16,000MPaであることを特徴とする。これにより、耐摩耗性と密着性を維持でき、高い抗菌性と高い骨伝導性を長期間維持した抗菌性部材を得られる。F-DLC膜は必ずしも基材の最表面全体を覆っている必要はなく、斑状に配置してもよい。
