20140048182 | SURFACE TREATMENT METHOD FOR METAL MATERIAL AND MOLD TREATED BY SURFACE TREATMENT METHOD - A surface treatment method for a metal material is provided which includes applying diluted sulfuric acid to a surface of the metal material that is composed primarily of iron, performing a heat treatment on the metal material in the presence of at least one of CO, CO | 02-20-2014 |
20120288622 | CASTING MOLD SURFACE TREATMENT METHOD - A surface treatment method includes covering a surface of a casting mold with a carbon film containing at least one type of nanocarbon selected from the group consisting of carbon nanocoils, carbon nanotubes and carbon nanofilaments, and further applying fullerenes to that surface. With this surface treatment method being performed on a surface (a cavity surface, etc. of a casting mold) making contact with a molten casting material such as aluminum, etc., sticking of the molten casting material to the mold is inhibited, release resistance of the product is reduced, and release effectiveness is improved. The release effectiveness lasts longer than in the case of a conventional carbon film. | 11-15-2012 |
20110223339 | METHOD FOR SURFACE PROCESSING - A method for a surface processing is provided. The method may include coating a surface of an object by a carbon coating including at least one type of a nano carbon selected from a carbon nano coil, a carbon nanotube and a carbon nano filament and applying liquid including fullerene to the carbon coating. | 09-15-2011 |
