摘要： PURPOSE:To extend the life and to make the maintenance easy by utilizing a porous sintered metal body as a framework, impregnating a solid lubricating material in the space in said framework, and reducing mechanical wear. CONSTITUTION:Rough particles of metal or alloy of aluminum, copper, and the like are uniformly filled in an appropriate mold such as a graphite mold and the like without pressure, and sintered in a furnace in the atmosphere with nonoxidizing or reducing properties such as nitrogen and the like, thereby a porous sintered metal body having a porosity of 20-60% is obtained. A solid lubricating material, which is only grease or a material in which more than one lubricants such as graphite powder, molybdenum disulfide, and the like are added to a grease, wax, and the like, is impregnated into the space in the framework of the sintered body. In this method, the mechanical wear can be reduced, the lives of the slider and a trolley wire can be extended, and the maintenability can be increased.

摘要： PURPOSE:To furnish with current collecting sliding material combining excellent mechanical strength and current collecting capacity of a metallic system and a superior lubricating property of a black lead system. CONSTITUTION:The desired current collecting sliding material can be obtained from a sintering body of mixed powder consisting of 30-60 weight % copper coating black lead powder, 3-20 weight % hard metallic powder, such as, iron, chrome or ferromolybdenum, the tin powder of the quantity that the ratio of tin to the sum of the whole copper quantity containing remaining copper powder and the quantity of tin, is 5-10 weight %, and remaining copper powder. Said copper coating black lead powder is produced by coating a surface of black lead powder with copper; for example, matter is preferably used which is manufactured by uniformly applying copper coating with approximate 3-5mu thickness to approximate 80-200 mesh granular artificial black lead powder as much as possible by means of a non-electrolytic plating method, an electroplating method, etc. Expected demanded characteristics can be satisfied according to current collecting sliding material mentioned above.

摘要： PURPOSE:To provide the material for a sliding current collector with reduced attacking property against a trolley wire and excellent wear resistance, by containng approx. 0.5-10wt% of nitride of titanium or ferrotitanium in the material. CONSTITUTION:Approx. 0.5-10wt% of titanium or ferrotitanium is nitrided beforehand and added to a base essentially containing Fe or Cu as main ingredient, the mixture is then molded and sintered, or approx. 0.5-10wt% of titanium or ferrotitanium is added in an untreated state to the base, the mixture is molded, and sintered in an atmosphere containing nitrogen or ammonia, thereby obtaining the sintered material for a current collector. Since its wear resistance can be thus improved by a nitrided layer and the area of the exposed nitrided layer on the slide surface is very small, the material has small attacking property against a trolley wire.

摘要： PURPOSE:To improve the machinability of sintered iron using no special means when sintering, by diffusing copper phase and lead phase into the crystal boundary of iron grains in the base material and by inhibiting the alloying of carbon from an atmosphere with the iron base metal. CONSTITUTION:0.2-3wt% lead and 0.5-5wt% copper in the form of free powder particles or alloy powder particles are mixed with iron powder to be molded and then the molded item is sintered in a non oxidizing atmosphere. Further, to the mixture, MnS powder and CaS powder may be added. It is best to carry out the sintering at a temperature which is sufficient to result in no chipping when the molded item is machined thereafter and at which the carbon component is hardly alloyed with the iron base metal. Lead and copper improve the machinability of the sintered body. Lead is alloyed with a part or the entire of copper to diffuse rapidly into gaps between iron grains and into the boundary of iron grains and to cover iron grains with the newly formed alloy, thereby inhibiting the alloying of caron with the iron grains. For attaining such effects, each content of lead and copper need exceed the above-mentioned each lower limit, respectively, but, on the other hand, when the content exceeds the upper limit corresponding to it, lead obstructs bonding between iron grains and is apt to result in the formation of defects in machining of the sintered body, while copper is excessively alloyed with iron so that the hardness of iron base metal is raised and the machinability of the sintered body is deteriorated.

摘要： PURPOSE:To provide the titled material having both of metallic material strength and MoS2-based excellent lubricating property which consists of sintered body of mixed powder, mainly copper powder and contg. each specific ratio of hard metallic powder such as Fe, Cr, etc., Sn, and copper-covered MoS2 powder of each specific ratio. CONSTITUTION:Cu-covered MoS2 powder is prepared, for example, by applying about 3-5mu thick Cu cover, as uniform as possible, on MoS2 powder of about 80- 350mesh. The Cu-covered MoS2 preferably consists of about 20-50wt% of Cu and about 50-80wt% of MoS2. Then, mixed raw material consisting of Cu powder including 1-15wt% of the Cu-covered MoS2, 3-20wt% of hard metal powder such as Fe, Cr, or ferromolybdenum, etc., and 5-13wt% of Sn is sintered, as follows. This mixed raw material is uniformly mixed by use of a V-type mixer, etc., is normally molded under about 2-4ton/cm and is sintered at about 700-900 deg.C in non-oxidizing atmosphere, so that the desired sliding material for current collector is produced.
