Abstract: A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. When the matrix of the thin plate is crystal-structure metal, the plate can be formed at room temperature, and when the matrix is metallic glass, the plate can be formed in a supercooled liquid state. Therefore the plate can be finished into a separator with an intended shape.

Abstract: The invention provides equipment for manufacturing a torque sensor shaft by forming a magnetostrictive region including a metallic glass coating in a predetermined pattern on a side face of a shaft-shaped workpiece. The shaft-shaped workpiece is rotatably attached on a conveying pallet. The conveying pallet is successively conveyed to each of work devices including a preheating device for the shaft-shaped workpiece, a thermal spraying device for forming a metallic glass coating on a side face of the shaft-shaped workpiece, a masking device configured to provide a covering corresponding to the pattern on the coating, and a shot blasting device configured to provide shot blasting directed toward the metallic glass coating including the covering. Preheating, thermal spraying, masking, and shot blasting are performed respectively on the shaft-shaped workpiece while rotating the shaft-shaped workpiece on the conveying pallet at each of the work devices.

Abstract: [Problem] To prepare a thin plate having excellent corrosion resistance, conductivity, and formability at low cost. [Solution] A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. An obtained thin plate has a conductive material component that exists, without dissolving, in a metal matrix exhibiting corrosion resistance by passivation, thereby having aforementioned characteristics.

Abstract: An apparatus for forming an amorphous coating film by jetting flame containing particles of a flame spray material from a flame spray gun toward a base material, causing the particles to be melted by the flame, and cooling both the particles and the flame with the means of a cooling gas before they reach the base material. The apparatus includes a tubular member provided among the path along which the flame is jetted that it surrounds the flame passing through a melting zone in which the particles are melted. The tubular member has a flow channel for the cooling gas, formed along and integrally to the tubular member.
