摘要： The surface of a metal is treated in a fluidized bed system, in which a hot rolled metal is continuously subjected to an in-line treatment to suppress the formation of scale on its surface or to remove the same therefrom, and then is introduced into a gaseous fluidized bed of a non-oxidizing gas, which contains metal or alloy particles having a low melting point, as fluidized particles, so as to bring the hot rolled metal into contact with the fluidized particles. As a result, the fluidized metal particles or alloy particles may be melted and solidified on the surface of the rolled metal to provide a coated layer of a metal or alloy having a low melting point on the surface thereof. In addition, during the surface treatment in the fluidized bed system, a heat treatment such as patenting or cooling may be applied concomitantly in combination therewith.

摘要： PURPOSE:To produce a Cu-based Pt-clad electrode having lowered electric resistance with a reduced amt. of Ti, etc., used at a reduced cost by interposing a middle layer of a corrosion resistant material contg. Ti, Zr, Nb or Ta between an inner Cu alloy layer and an outer Pt alloy layer. CONSTITUTION:An inner Cu or Cu alloy layer ensuring structural strength of an electrode and acting as an electrifying material is clad with a middle layer of a corrosion resistant material contg. Ti, Zr, Nb or Ta to prevent the leaching of the Cu or Cu alloy. An outer Pt or Pt alloy layer insoluble in a plating soln. and an electrolytic soln. is further formed on the periphery of the middle layer. The resulting clad pipe is made flat by pressing and formed into a prescribed electrode shape by bending. When the clad pipe is formed so that both ends are positioned above the surface of a plating soln. or an electrolytic soln., the exposed parts of the inner layer are not immersed in the soln.

摘要： PURPOSE:To furnish a resistance welding electrode having the long service life excellent in heat resistance, high-temperature strength, electrical conductivity and wettability resistance for molten Al and having the electrode tip part which is hardly deformed. CONSTITUTION:A cylindrical intermediate layer 2 made of ingot metal is first fitted into an outer layer 1 made of oxygen free copper formed cylindrically and powder having specified copper alloy composition is filled into this intermediate layer 2 to obtain a billet. This billet is then subjected to homogenizing treatment at 850-1000 deg.C, then, extruded under condition of an extrusion ratio of 10 at 700-950 deg.C and then, cooled up to =2 deg.C/sec. The billet is then subjected to cold working at the working rate of >=20%, then, heated for more than thirty minutes at 450-550 deg.C and subsequently, cooled up to

摘要： PURPOSE:To form the insoluble electrode for electrolysis which does not elute metal components by forming an anode surface to be used for cation electrodeposition coating of an Ni-Nb intermetallic compd. layer and constituting the base material of Nb. CONSTITUTION:A coating bath 2 consisting of a cation electrodeposition coating material is filled in a cell 1 for electrodeposition and a cylindrical diaphragm chamber 3 closed at the bottom end is provided in this coating bath 2. The diaphragm chamber 3 is formed to have a diaphragm of an ion permeable material and diaphragm water 4 (contg. an org. acid of a low concn.) is passed in the diaphragm chamber 3. A material 11 to be coated is immersed in the coating bath 2 of this constitution and an electrode 10 (stainless steel, etc.) is installed in the diaphragm water 4. A DC current is passed to the material 11 as cathode and the electrode as anode to form the cation electrodeposition coated film on the surface of the material 11. The electrode 10 is the insoluble electrode having the structure consisting laminating a base material 23 consisting of Nb on a support 24 consisting of a good conductor selected from Cu, Al, Fe and further, laminating an Ni layer 22 on the base material 23, then forming the Ni-Nb intermetallic compd. layer by diffusion of the Ni layer 22, and finally laminating a sheath 21 consisting of a carbon steel thereon.

摘要： PURPOSE:To form a deep groove and to ensure a desired heat conductivity by forming a drawing die, a grooved plug and a retaining ring for rolled member with a shape memory alloy selectively. CONSTITUTION:The drawing die 2 is formed with the shape memory alloy, after passing through the metal pipe 1 by the same outer diameter of the grooved plug 4 or larger diameter of it, heated and reduced its diameter. More, the grooved plug 4 and the retaining ring 7 for rolled member 6 are formed with the shape memory alloy, the grooved plug 4 is inserted into the metal pipe 1 in the state of having a smaller diameter than the pipe. Then, after the retaining ring 7 for the rolled member 6 is set on the position where it is corresponding to the grooved plug 4 and the rolled member 6 does not press the metal pipe 1, the grooved plug 4 and the retaining ring 7 are heated to expand the diameter of the grooved plug 4 and to contract the diameter of the retaining ring 7 simultaneously. Thence, the inner surface of the metal pipe 1 is expanded to the same diameter of the groove depth or more by the grooved plug 4 to work grooving the inner surface.
