    • A titanium electrode material comprising a titanium alloy substrate containing a noble metal element selected from an element belonging to the platinum group, Au and Ag and a mixed layer formed on the surface of the substrate, wherein the mixed layer has an average thickness of 200 nm or lower and contains the noble metal element deposited from the titanium alloy substrate and titanium oxide, where the surface of the mixed layer and the titanium alloy substrate have a conductivity of 12 mOmega.cm^2 or lower in terms of contact resistance as determined by the method described below. The contact resistance is determined as follows: a platy titanium alloy material having the mixed layer formed thereon is sandwiched by a pair of copper electrodes with the contact area of 1 cm^2 through a carbon cloth having an average thickness of 0.3 mm, a current of 7.4 mA is passed between the pair of cupper electrodes while loading a surface pressure of 5 kg/cm^2 on both surfaces of the titanium alloy material to measure an amount of voltage drop produced between the carbon cloths on a four-terminal resistance meter, and a contact resistance is then calculated based on the resulting value.
    • 一种钛电极材料,其包含含有选自属于铂族的元素,Au和Ag的贵金属元素的钛合金基板和形成在基板的表面上的混合层,其中该混合层的平均厚度为200nm 或更低,并且包含从钛合金基底和氧化钛沉积的贵金属元素,其中混合层和钛合金基底的表面的接触电阻的电导率为12mOmega.cm 2或更低,如由 下面描述的方法。 接触电阻确定如下:将其上形成有混合层的板状钛合金材料通过平均厚度为0.3mm的碳布被一个接触面积为1cm 2的铜电极夹在一起,电流 在一对铜电极之间通过7.4mA的电流,同时在钛合金材料的两个表面上加载5kg / cm 2的表面压力,以测量四端电阻计上的碳布之间产生的电压降的量 ,然后基于所得到的值来计算接触电阻。
