To provide an anodic oxidation method, a titanium oxide film manufacturing method and a catalyst carrying method which is suitable, for example, for anodic oxidation of aluminum, titanium and catalyst carrying on the surface of alumite (registered trademark), capable of generating an oxide film at a low cost and rapidly by eliminating the use of a strongly acid or strongly basic electrolytic solution and using a carbonated water as an electrolytic solution, capable of controlling the sealing treatment of oxide film through a simple method, capable of effecting the oxide film dyeing and catalyst carrying rationally and easily, and capable of effecting the catalyst carrying safely and surely without eroding a base material. An object () to be treated is electrolyzed in an electrolytic solution received in a treatment vessel () serving the object () as an anodic electrode. It is an anodic oxidation method in which an oxide film is generated on the surface of the object (). A carbonated water of a predetermined acid concentration generated by dissolving a pressurized carbon dioxide in a predetermined quantity of water () is used as the electrolytic solution.

A method for activating the surface of a base material and an apparatus thereof, which is suited to be utilized for pretreatment in electrochemical treatment such as, for example, electroplating or the like, in which the surface of a base material such as metal can be subjected to degreasing treatment and oxide film removing treatment simultaneously, efficiently and rationally, in which productivity can be enhanced and the equipment cost can be reduced, and in which a waste solution can be rationalized so that the solution can be reutilized and the environmental pollution can be prevented. A method for activating the surface of a base material in which the surface of a member to be treated is subjected to degreasing treatment or oxide film removing treatment. Pressurized carbon dioxide is dissolved in a predetermined quantity of water, thereby preparing an oxide film removing solution having a predetermined acidic concentration.

Method for activating surface of base material and apparatus thereof

There is provided a metal thin film comprising a metal plate and a diamond particle dispersed in the metal plate. According to the present invention, the metal thin film has a film thickness of 5 nm to 35000 nm. The diamond particle is dispersed almost homogeneously over the direction of the film thickness of the metal thin film. The metal thin film has the diamond particle at a concentration of 1 to 12%. According to the present invention, based on conversion into an equivalent circle, the diamond particle has a first particle size distribution with respect to a first particle of a first particle size of 16 nm or less, at a first number average existence rate of 50% or more; the diamond particle has a second particle size distribution with respect to a second particle having a second particle size of 50 nm or more, at a second number average existence rate of substantially 0%; and the diamond particle has a third particle size distribution with respect to a third particle having a third particle size of 2 nm or less, at a third number average existence rate of substantially 0%.
