Patent number: 7378134Abstract: Disclosed is a method of forming a high-temperature corrosion-resistant film, which comprises placing a container containing a film-forming fine powder and a target member capable of being heated by an electric current heating process, in an atmosphere-controllable treatment chamber, and floating the fine powder and subjecting the target member to the electric current heating process to allow vapor of the fine powder generated by the heating to be diffused into the target member from a surface thereof so as to form a diffusion film layer, and allow the floated fine powder to be attached onto the surface so as to form a fine-powder film layer on the diffusion film layer. The target member may be masked to form the film only in a non-masked region of the target member. Alternatively, a specific region of the target member may be cooled at a temperature precluding the film formation to prevent the film from being formed in the specific region.Type: GrantFiled: February 9, 2004Date of Patent: May 27, 2008Assignee: Japan Science and Technology AgencyInventors: Toshio Narita, Shigenari Hayashi

Patent number: 5310476Abstract: An adherent protective coating of a refractory material is produced on the surface of carbonaceous, refractory, ceramic, metallic or other materials serving as components of electrolytic cells operating at high temperature, by applying to such surfaces a well chosen micropyretic reaction layer from a slurry, which when dried is ignited to initiate a self-sustaining micropyretic reaction, along a combustion front, to produce condensed matter forming such refractory protective adherent coating. The slurry is preferably applied in several layers, the first layer(s) to facilitate adherence and the last layer(s) to provide protection, and may contain some preformed non-reactant materials. The electrolytic cells whose components require such coatings are especially those operating at high temperature with a molten salt electrolyte, particularly those for the production of metals, aluminium being the most important.Type: GrantFiled: April 1, 1992Date of Patent: May 10, 1994Assignee: Moltech Invent S.A.Inventors: Jainagesh Sekhar, Vittorio de Nora
