摘要： A method for treating an implant material having excellent biocompatibility, particularly, a method and an apparatus for treating a dental implant material. A method and an apparatus for treating an implant material having excellent biocompatibility, in which a surface-roughened implant material containing titanium and a titanium alloy is immersed in electrolyzed ozone water, and the electrolyzed ozone water is held at normal temperature, thereby preventing contamination due to adsorption of carbide on the surface of the implant material and imparting hydrophilicity.

摘要： The present invention aims to provide an activated cathode enabling a long-time stable operation with hydrogen overvoltage maintained at a low value, keeping a high remaining rate of the catalyst element after a cease of operation for a short-circuiting and after an electrolysis operation at a high current density, restricting catalyst loss to a little, and having a strong resistance to contamination caused by electrolyte impurity elements. The present invention relates to a cathode for hydrogen evolution with a catalyst layer formed on the cathode substrate, having, at least, three elements comprising platinum, cerium and palladium, as essential element, in a state of metal, metal oxide, or hydroxide, contained, where the mole fraction of respective element being x, y, and z, within a range of 5 mol %≦̸x≦̸90 mol %, 5 mol %≦̸y≦̸55 mol %, 5 mol %≦̸z≦̸65 mol %.
