A method for surface treatment of a metal material in a powder state is provided, the method including obtaining a powder formed from a plurality of particles of the metal material to be treated; and subjecting the powder to an ion implantation process by directing a beam of singly-charged or multi-charged ions towards an outer surface of the particles, the beam being produced by a source of singly-charged or multi-charged ions, whereby the particles have an overall spherical shape with a radius (R). There is also provided a material in a powder state formed from a plurality of particles having a ceramic outer layer and a metal core, the particles having an overall spherical shape.

An object of the invention is to provide: a two-phase alloy as a metal material that can be preferably utilized under circumstances of a temperature range and a high corrosion as in an oil well, the two-phase alloy having a high corrosion resistance and good mechanical properties that are equivalent or more than those of conventional ones, and saving a cost; a product of the two-phase alloy; and a method for producing the product. There is provided a two-phase alloy containing Cr as a major component and including two phases of an austenite phase and a ferrite phase in a mixed state. The alloy has a chemical composition containing: 34-70 mass % of Cr; 17-45 mass % of Ni; 10-35 mass % of Fe; 0.1-2 mass % of Mn; 0.1-1 mass % of Si; and impurities. The total content of the Ni and the Fe is 30-65 mass %.

An apparatus and method for supporting a tubular medical device, such as a stent or scaffold, includes a rod disposed between two collets. The rod can be shaped to form a range of different size or length helical supports to support a wide range of tubular medical devices. The rod is shaped into a full or partial helix by rotating one of the collets relative to the other.

An apparatus is for forming powder, and includes an energy source for emitting at least one energy beam onto a workpiece, the energy beam being configured to melt the workpiece, at least in part, to form at least one pool of molten material on the workpiece. The apparatus is configured to exert a force on the workpiece causing at least a bead of molten material to be ejected from the pool and solidify to form a particle of powder.
