    Abstract: A borided titanium article can include a titanium mass having titanium monoboride whiskers infiltrating inward from a surface of the titanium mass to form an integral surface hardened region. The titanium mass can be almost any titanium based metal or alloy such as high purity titanium, commercial grade titanium, α-titanium alloy, α+β titanium alloy, β-titanium alloy, titanium composite, and combinations thereof. Borided titanium articles can be formed by methods which include providing a titanium mass, contacting a surface of the titanium mass with a boron source medium, and heating the titanium mass and boron source medium to a temperature from about 700° C. to about 1600° C. The boron source medium can include a boron source and an activator selected to provide growth of titanium monoboride whiskers. The boron source medium can be provided as a solid particulate mixture, liquid mixture, or as a gaseous mixture. During heating, boron from the boron source infiltrates into the titanium mass and forms titanium monoboride whiskers which improve the surface hardness, wear resistance, oxidation resistance, and corrosion resistance of the treated surface. The titanium monoboride whiskers can be controlled to have the desired dimensions, depending on the application requirements. Boriding titanium surfaces using these methods, provides a relatively inexpensive and effective process for improving the surface properties of titanium which are then useful in a wide variety of applications.

    Abstract: An object of the present invention is to easily eliminate fumes inside a chamber, so as to improve a positional accuracy of irradiation with a light beam and a machining accuracy in a method for manufacturing a three-dimensional shaped object. A stacked-layers forming device 1 includes a powder layer forming unit 3, a light beam irradiating unit 4, a base 22 which is fixed and on which a powder layer 32 is formed, a lifting/lowering frame 34 which surrounds the circumference of the base 22 and is freely capable of being lifted and lowered, a cover frame 36 which has a window 36a allowing transmission of light beam in its top surface, and whose bottom surface is opened, and which is disposed on the lifting/lowering frame 34 to form a chamber C, and a gas tank 71 for supplying an ambient gas. The lifting/lowering frame 34 is lowered to reduce the volume of the chamber C, so as to discharge fumes generated inside the cover frame 36, which performs replacement with the ambient gas. Since the volume of the chamber C is reduced, it is possible to easily eliminate the fumes, which makes it possible to improve the positional accuracy of irradiation with the light beam L, and the machining accuracy.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a three-dimensionally shaped object wherein the removal of fumes in a chamber can be easily performed, and the emission position precision of a light beam and processing precision are improved. SOLUTION: A multi-layer molding device 1 is provided with: a powder layer forming part 3; a light beam emission part 4; a fixed base 22 at which a powder layer 32 is formed; an elevating/lowering frame 34 surrounding the outer circumference of the base 22 and further freely elevatable/lowerable; a covering frame 36 in which the upper face is provided with a window 36a permeating a light beam and also the lower face is released, and which is arranged on the elevating frame 34 so as to form a chamber C; and a gas tank 71 feeding an atmospheric gas. By descending the elevating frame 34, the volume of the chamber C is reduced to exhaust fumes generated in the covering frame 36, so as to be replace by an atmospheric gas. Since the volume of the chamber C is reduced, the removal of fumes can be easily performed, and the emission position precision of a light beam L and processing precision are improved.
