Patent number: 7736442Abstract: 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.Type: GrantFiled: October 18, 2007Date of Patent: June 15, 2010Inventors: Hideo Yoshida, Nobuyoshi Sato, Takeshi Sako, Masato Sone, Kentaro Abe, Kiyohito Sakon

Patent number: 7718010Abstract: The present invention related to a method for treating a surface with a gel, as well as to a treatment gel. The treatment may be a decontamination, etching or surface degreasing treatment, for example. The method comprises in this order, the following steps: applying the treatment gel on the surface to be treated, maintaining the treatment gel on the surface to be treated at a temperature and relative humidity such that the gel dries by breaking up and that it has the time to treat the surface before forming a dry and solid residue, and removing the dry and solid residue from the treated surface by suction or brushing. The gel comprises a viscosing agent, a treatment agent and optional an oxidizing agent.Type: GrantFiled: August 9, 2005Date of Patent: May 18, 2010Assignees: Commissariat a L'Energie Atomique, Compagnie Generale des Matieres NucleairesInventors: Sylvain Faure, Bruno Fournel, Paul Fuentes, Yvan Lallot
