摘要： PURPOSE:To coat ultrafine grain powder of a metal or metallic compd. to be used for joining metals, etc. to the joint part of members to be joined in a clean state without decreasing the activity thereof by inserting the members to be joined in the state of shielding said members from the atm. air into a conveying path for the ultrafine particles of said metal or metallic compd. CONSTITUTION:The ultrafine grain powder of a metal or metallic compd. which has high activity and is used for joining metals and ceramics is coated on members to be joined and is joined by sintering and melting at a low temp. Since the ultrafine grain powder decreases the activity thereof by combining with O2 and N2 in the atm. air, the powder is coated to the joint part in a clean state. A vacuum valve 2 and a connecting pipe 3 are connected to a path 1 for conveying the ultrafine particles of the metal, etc. and a sampler 7 is connected to the pipe 3 for the above-mentioned purpose. The valve 2 is closed and after the inside of the pipe 3 is evacuated to vacuum by a vacuum valve 5, the valve 5 is closed and the valve 2 is opened and at the same time a convering member 9 is pushed by a rod 9 moved by an iron piece 10 moving with the movement of of a magnet 1, by which the member 9 is pushed into the path 1 and the ultrafine particles in the path 1 are coated on the surface of the member 9 in the state of shielding said member from the atm. air.

摘要： PURPOSE:To improve bond properties and to heighten reliability and economical efficiency of a heat exchanger, as well as to prevent the pores of heat transmitting plates from clogging, by monolithically bonding laminate material consisting of copper heat transfer plate having pores and stainless steel spacer being laid alternately, by diffusion bonding. CONSTITUTION:A laminate material 1 is compoaed of copper heat transfer plates 1A provided with a number of pores and stainless steel spaces 1B, being laid alternately and bonded monolithically by diffusion bonding. The heat transfer plate 1A and the spacer 1B are worked into specified forms by punching using dies of specified forms. The numericals 3 and 4 are an upper and a lower headers, between which the laminate material 1 is interposed. The above-mentioned diffusion bonding is performed under the following conditions: the degree of vacuum is 10 Torr, the bonding temperature is 900 deg.C, the bonding time is 1hr, and the bonding pressure is 1kg/mm. . The lamination by the method of diffusion bonding is to bond the material by relative diffusion of elements without melting a base material, so that a number of pores provided to the heat transfer plates 1A are prevented from clogging, and the bonded part which is highly reliable can be obtained.

摘要： PURPOSE:To obtain a lightweight sintered metallic material with high ductility, superior wear resistance and superior frictional characteristics by using specified percentages of an Fe alloy and Al or an Al alloy as principal components. CONSTITUTION:A metallic material for sintering is composed of 5-80wt% Fe alloy, 20-95wt% Al or Al alloy and a small amount of impurities. This mixture is sintered at about 400-640 deg.C sintering temp. and >=about 10 mm.Hg vacuum degree to obtain a sintered metallic material capable of being plastically worked even at ordinary temp.

摘要： PURPOSE:To form molded parts of uniform density by exerting face pressure and uniform side pressure thereupon with soft rubber as a pressure medium. CONSTITUTION:When axial load is exerted upon soft rubber 15 via an upper punch 9 by means of a loading device, side pressure is generated by the phenomena wherein the rubber is compressed axially and is expanded radially. Said side pressure is exerted upon powder through a vessel 11 having plasticity. When the rubber 15 is compressed axialy, and the end face 9a of the punch 9 contacts with the end face 18a of an elastic material 18, the powder 2 is exerted with uniform axial compressive load upon its surface via the material 18. In such a way, the powder 2 is formed into a molding of high density having no variance by the loading face pressure and side pressure. The vessel 11 to be packed therein with the powder 2 is made of a synthetic resin having plasticity and having a small coefft. of friction with the rubber 15, for example, polytetrafluoroethylene or nylon.

摘要： PURPOSE:To form surface hardened layers of high erosion resistance by irradiating plasma jet flames using an inert gas added with nitrogen as a working gas to steam turbine blades consisting of 12% Cr alloy steel. CONSTITUTION:Plasma jet flames 5 are irradiated by using a plasma touch 6 to steam turbine blades made of 12% Cr alloy steel. An inert gas such as Argon added with 30% gaseous nitrogen is used as a working gas and an 100% gaseous nitrogen is used as a shielding gas 4. Plasma arcs are generated by flowing electric current between a nozzle 2 and a tungsten electrodes 1 and plasma jet flames 5 are irradiated to heat the blades 7 without melting the same, whereby the hardened layers of high erosion resistance are formed on the surfaces of the blades 7 in a short time.
