摘要： PURPOSE:To improve operability of an adhering stage in the stage of adhering a powder alloy sheet for forming a sintered alloy layer to the surface of a metallic base body by coating respectively the 1st liquid and 2nd liquid of a two pack adhesive agent to the surface of the metallic base body and the powder alloy sheet. CONSTITUTION:The alloy powder sheet consisting of the powder of the metal or alloy having excellent resistance to wear, heat and oxidation and resin binder is adhered to the surface of the metallic base body in order to form the sintered layer having such characteristics to said surface. The sheet is heated to a high temp. to form the sintered layer on the surface of the metallic base body. The 1st liquid of the two pack adhesive is in this case preliminarily coated on the metallic base body and the 2nd liquid on the powder alloy sheet and the adhesion is effected simply by pressing the surfaces on which the 1st liquid and 2nd liquid are coated as and when needed and therefore the extremely simple and efficient execution of the adhering stage is made possible.

摘要： PURPOSE:To impregnate lead to the desired surface of a ferrous sintered alloy without pressurization by interposing a sheet consisting of a powder alloy which improves wettability between the ferrous sintered alloy and a lead material and heating the same. CONSTITUTION:A sheet 2 manufactured by kneading alloy powder of Pb-Sn or the like which improves wettability between a ferrous material and lead and a resin binder is adhered to the surface of a ferrous sintered alloy and a lead material 3 is adhered onto said sheet. The adhered material is placed on a carriage 4 and is carried into a heating furnace where the material is heated to the temp. higher than the m.p. of the lead material 3. The alloy powder of the sheet 2 impregnates the inside of the alloy 1, thus improving the wettability between the alloy 1 and the lead 3. The ferrous sintered alloy 1' taken out of the furnace 5 is thus impregnated with the lead only in the surface to which the sheet 2 is adhered.

摘要： PURPOSE:To make it possible to form a sintered alloy layer necessary for almost the entire surface of the local part of a matrix material, by a method wherein alloy powder sheets each forming a liquid phase at a sintering temp. are laminated to both sides of a sheet containing an alloy powder forming no liquid phase at the sintering temp. and respective thicknesses thereof are made adequate. CONSTITUTION:An alloy powder sheet prepared by bonding an alloy powder with synthetic resin having stickiness is constituted as mentioned hereinbelow. That is, sheets each containing an alloy powder forming a liquid phase in a sintering temp. range are respectively laminted to both sides of a sheet containing an alloy powder forming no liquid phase in the sintering temp. range to form a multi-layered structural sheet having thee layers or more. In this case, the thicknesses of the central sheet and both side sheets are set to such a predetermined ratio that the multi-layered structural sheet does not generate warpage with respect to a matrix material during sintering.

摘要： PURPOSE:To mold the specified formed cam part having an abrasion resisting alloy layer on its surface, by constituting a cam sliding part in a way of sintering a pad member made of kneading abrasive resisting alloy powder and an abrasive. CONSTITUTION:Abrasive resisting alloy powder and acrylic system adhesive are kneaded, forming a sheet, and a pad member 5 provided with a through hole 6 is installed in this sheet, while a cam base member 1 forming an interconnecting hole 3 in the specified position of a cam part 1a is prepared for, then the pad member 5 is applied to the cam base member 1 and simultaneously a pin-form perforated member 4 is inserted into the through hole 6 of the pad member 5 and insertedly locked to the interconnecting hole 3 of the cam base member 1 and, after this perforated member is heated for more than five minutes long at a temperature of 150-380 deg.C in a nonxidating ambience, it is heated and sintered, thus an abrasive resisting sintered layer is formed on the cam part, whereby an oil passage is formable owing to the perforated member.

摘要： PURPOSE:To obtain a metallic layer having wear resistance and less tendency to damage on the other material on the surface of a light alloy member by adhering tightly a molding of wear-resistant eutectic alloy powder one surface of a porous metallic member and pouring a molten aluminum alloy to the other surface. CONSTITUTION:A molding 3 consisting of wear-resistant eutectic alloy powder contg. an element having excellent diffusibility (for example, Mo, B, P) with a porous metallic member 2 as a constituting element is tightly adhered to one surface of said member and is sintered by heating. Molten aluminum is then poured to the other surface of the member 2 and is cast thereon. The metallic layer having wear resistance and less tendency to damage on the other material is thus obtd. on the surface of the light alloy member.

摘要： PURPOSE:To economize energy for a heat treatment and to obtain a member having vibration-damping property by adhering a wear resistant powder alloy sheet onto the surface of a metallic base material consisting of a vibration-damping material, sintering the same and subjecting the material to a vibration damping heat treatment including a preliminary heat treatment in the midway of a temp. decrease. CONSTITUTION:A powder alloy sheet manufactured by kneading wear resistant alloy powder and resin binder is adhered to the surface of a metallic base body consisting of a vibration-damping material for which wear resistance is required. The adhered member is sintered by heating up to the sintering temp. to form a sintered metallic layer. The material is held at a prescribed temp. in the midway of the temp. decreases as a preliminary heat treatment in the stage of starting the vibration-damping heat treatment from the sintering temp. and after the material is hardened and quickly cooled, the material is subjected to a tempering treatment which is a post treatment. The metallic part having wear resistance and vibration-damping property on the desired surface is obtd. by the above-mentioned method. Since the heating for the purpose of hardening in the vibration-damping heat treatment is not required, the energy as a whole is economized.

摘要： PURPOSE:To form a uniform hardened layer in which no chilled layer exists practically by degraphitizing a surface layer part of cast iron member and thereater irradiating a laser beam or an electron beam on said surface. CONSTITUTION:A surface layer part of cast iron member is degraphitized and a laser beam or an electron beam is irradiated on the surface that graphite has removed therefrom to harden said surface. By this treatment, a hardened layer consisting of a uniform martensite structure without formation of a chilled layer can be formed locally and deeply. In the metallic structure subjected said treatment, the ground becomes a fine martensite ground 7 and the part where the graphite has been in existence initially remains as an eliminating part 4 of the graphite at said ground 7. Some quantities of oxides 8 are observed at said part 4 and remaining graphite 10 is observed at the deep part from the surface 9.
