摘要： A method is described for welding a sintered molded body (1) which comprises a residual porosity and which is molten in the region of the later weld seam (3) by a laser beam (4). In order to obtain dense weld seams it is proposed that during the melting of the molded body (1) the atmospheric oxygen is bound at least substantially by a deoxidizer from the pores of the molded body (1) in the area of the weld seam and is embedded in the form of finely dispersed oxides in the weld seam (3).

摘要： A sintered connecting rod for an internal combustion engine comprises a connecting rod eye (1) for receiving a piston pin, a connecting rod big end (3) for holding the crank pin and a shaft (2) made of two diverging longitudinal bridges (4) which are optionally stiffened by a connecting bridge (5) and whose mutually facing bridge flanks (11) are connected in the zone of the connecting rod big end (3) by a central concave rounding (9). In order to ensure advantageous loading conditions it is proposed that the longitudinal bridges (4) of the shaft (2) diverge from the connecting rod big end (3) to the connecting rod eye (1).

摘要： The invention relates to a method for producing a molded body made of sintered steel, with a sintering powder on the basis of iron being mixed with a master alloy powder containing nickel, boron and iron, and with the powder mixture being pressed into a formed body before the formed body is sintered under the conditions of a liquid-phase sintering with a volume share of liquid phase up to 15%. In order to improve the impact strength, it is proposed that the boron content of the powder mixture is between 0.03% and 0.2% by weight at a boron share of the master alloy powder of less than 10% by weight, that the weight ratio between the nickel and the boron share of the powder mixture exceeds 5 and that the master alloy powder has an average particle size of between 10 and 90 μm.

摘要： The invention describes a component unit comprising at least one component (3), in particular a molded component (4), made from a powder or powder mixture containing metallic and optionally non-metallic components produced by compressing this powder or powder mixture, followed by sintering. At least one surface portion (12) of the component (3) which co-operates with another surface portion (13) of another component (14, 22) when pressure force acting between the two surface portions (12, 13) is applied is coated with an anti-friction varnish (2). The invention further relates to a method of producing such a component (3, 14, 22) with the anti-friction varnish (2).
