Abstract:
(EN) A titanium material which is provided with: a base material; and a surface modification layer that is formed on the base material. The base material contains, in mass% or in mass ppm, 0.010-0.100% of Fe, 0.005-0.110% of O, more than 1.0 ppm but 5,000 ppm or less of Al and 0-0.25% of one or more elements selected from among Au, Ag, Pt, Pd and Ru, with the balance being made up of Ti and impurities. The impurities contain 0.015% or less of C, 0.020% or less of N and 0.015% or less of H. The surface modification layer comprises a first layer that has a composition ratio of (Ti, Al)(C, B)m (wherein 0.5 ≤ m ≤ 1.5). This titanium material is capable of maintaining low contact resistance.
(FR) L'invention concerne un matériau de titane qui comprend : un matériau de base ; et une couche modificatrice de surface qui est formée sur la surface du matériau de base. Le matériau de base contient, en % en poids ou ppm en poids, de 0,010 à 0,100 % de Fe, de 0,005 à 0,110 % de O, plus de 1,0 ppm mais 5 000 ppm ou moins d'Al et de 0 à 0,25 % d'un ou de plusieurs éléments choisis parmi Au, Ag, Pt, Pd et Ru, le reste étant constitué de Ti et d'impuretés. Les impuretés contiennent 0,015 % ou moins de C, 0,020 % ou moins de N et 0,015 % ou moins de H et la couche modificatrice de surface comprend une première couche ayant un rapport de composition (Ti, Al)(C, B)m (où 0,5 ≤ m ≤ 1,5). Ce matériau à base de titane est capable de conserver une faible résistance de contact.
(JA) 基材と、前記基材上に形成された表面改質層を備えるチタン材。前記基材は、質量%または質量ppmで、Fe:0.010~0.100%、O:0.005~0.110%、Al:1.0ppmを超え5000ppm以下、ならびにAu、Ag、Pt、Pd、およびRuの1種または2種以上:0~0.25%を含有し、残部がTiおよび不純物からなる。前記不純物は、C:0.015%以下、N:0.020%以下、およびH:0.015%以下を含有する。前記表面改質層は、(Ti、Al)(C、B)(0.5≦m≦1.5)の組成比を有する第1層を含む。このチタン材は、低い接触抵抗を維持することができる。
