摘要： PURPOSE:To show both characteristics of a martensitic phase and a ferritic phase by impregnating copper into a specified sintered stainless steel. CONSTITUTION:For example, the powder of stainless steel equivalent to SUS430L is used for the formation of a ferritic phase and the powder of stainless steel equivalent to SUS 410L is used for the formation of a martensitic phase to form sintered stainless steel constituted of 20 to 50vol.% martensitic phase and the balance ferritic phase. This is brought into contact with a sintered body, e.g. of copper or a copper allay, and impregnation is executed at 900 to 1200 deg.C for 30 to 90min in a reducing atmosphere. The martensitic phase is incorporated with, by weight, 10 to 15% Cr and the ferritic phase with 16 to 30% Cr. The copper alloy is incorporated with at least one kind among Pb, Zn, Sn, Al and Ni. Thus, it can suitably used for the material requiring wear resistance or the like in a high temp. oxidation atmosphere.

摘要： PURPOSE:To provide a sintered friction material which does not cause seizing and makes little abnormal noise during sliding movement against a frictional surface and has excellent initial sliding properties, prepd. by forming a phosphate film and an MoS2 film on the surface of a specified sintered iron alloy. CONSTITUTION:A sintered iron alloy is prepd. by adding 0.2-0.8wt% graphite and 0.5-6wt% MoS2 to an alloy steel consisting of 0.4-1wt% Mn, 0.8-1.25wt% Cr, 0.15-0.35wt% Mo and the balance of iron and sintering the formed iron alloy at 1,100-1,200 deg.C in a non-oxidizing atmosphere, followed by cooling. The iron alloy is soaked in a mixed soln. of phosphate of a divalent metal and orthophosphoric acid, treated at 90-100 deg.C for 10-15min, washed with hot water and dried to form a phosphate film in the thickness of 0.5-30g/m on the surface. A coating soln. contg. a liquid organic binder obtained by dispersing 10- 30wt% MoS2 which has a purity of 99% or higher and in which particles with a diameter of 50mu or smaller account for 85% or higher, is applied over the phosphate film, followed by baking to form a 3-20mu thick film of MoS2.
