Latest Patents

Kodama's latest patents include innovative processes and compositions related to hard alloys. One of his notable inventions is a hard alloy containing molybdenum. This invention comprises two phases: a hard phase consisting of at least one compound with a simple hexagonal crystal structure, selected from mixed carbides, carbonitrides, and carboxynitrides of molybdenum and tungsten. The binder phase includes elements such as iron, cobalt, and nickel. The hard phase is prepared by carburizing an (Mo, W) alloy, which is obtained by reducing oxides of molybdenum and tungsten. The alloy features coarse particles with a mean size of at least 3 microns and maintains a uniform molybdenum to tungsten ratio.

Another significant patent by Kodama is a process for producing a hard solid solution containing molybdenum. This process involves preparing an alloy powder consisting of a solid solution of molybdenum and tungsten, adding carbon to form (Mo, W).sub.2 C and/or (Mo, W).sub.2 (CN), and heating the mixture to stabilize these compounds. This innovative approach enhances the properties of the resulting hard alloys.
