| 148237000 | Refractory metal (i.e., Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W) or refractory base alloy | 6 |
| 20100139812 | CASE HARDENING TITANIUM AND ITS ALLOYS - An article of titanium or a titanium-based alloy is case hardened by heat treatment at a temperate of 750° C. to 850° C. and at a pressure in the order of atmospheric pressure in a diffusion atmosphere. The diffusion atmosphere consists of a carrier gas such as argon which does not react chemically with the article in the said temperature range, and carbon monoxide. The concentration of carbon monoxide in the oxygen diffusion atmosphere is in the range of 20 volumes per million to 400 volumes per million. | 06-10-2010 |
| 20100200120 | Conductive film, corrosion-resistant conduction film, corrosion-resistant conduction Material and process for producing the same - A conductive film comprises a phosphide particle coated film formed by attaching raw material particles including phosphide particles comprising a compound of Ti and/or Fe, and P to a surface of a substrate material. This conductive film exhibits good corrosion resistant conductivity, and can be easily formed at low costs because of comprising the phosphide particle coated film. A corrosion-resistant conduction film comprises an iron-containing titanium phosphide layer containing Ti, Fe and P as essential basic elements. A corrosion-resistant conduction material having this corrosion-resistant conduction film on a surface of a substrate exhibits good corrosion resistance or conductivity. This corrosion-resistant conduction material can be obtained, for example, by a process comprising a plating step of forming an Ni plating layer on a surface of a Ti-based material substrate and a nitriding step of applying nitriding treatment to the Ti-based material substrate after the plating step at not more than 880 deg. C. | 08-12-2010 |
| 20110214785 | METHOD FOR FORMING A TUBULAR MEDICAL DEVICE - A method and process for at least partially forming a medical device that is at least partially formed of a metal alloy which improves the physical properties of the medical device. | 09-08-2011 |
| 20120325374 | DECORATIVE COMPONENT, TIMEPIECE, AND MANUFACTURING METHOD OF DECORATIVE COMPONENT - To provide a decorative component, a timepiece, and a manufacturing method of the timepiece capable of improving workability for color development and of enhancing decorativeness. A surface of an oscillating weight | 12-27-2012 |
| 20130240090 | METHOD FOR CARBURIZING TANTALUM CONTAINER - Provided is a method for carburizing a tantalum container which can easily control the carburization thicknesses of various portions of the tantalum container and carburize the tantalum container with a uniform thickness. A method for carburizing a tantalum container | 09-19-2013 |
| 20130248051 | METHOD OF FORMING RIGID LAYER ON TITANIUM AND TITANIUM ALLOY HAVING RIGID LAYER FORMED BY THE SAME - Disclosed is a method capable of inexpensively forming a gradient-hardened rigid layer which has characteristics of functionally graded material on the surface layer of titanium. The method includes (a) injecting titanium into a heat treatment apparatus and performing ventilation to maintain an atmospheric pressure of 10 | 09-26-2013 |
