    Abstract: PROBLEM TO BE SOLVED: To provide a thrust bearing of a turbocharger for an internal combustion engine excellent in seizure resistance by controlling the major axis direction of a needle Mn-Si based compound dispersed in the brass ground of a copper alloy.SOLUTION: The major axis direction of the needle Mn-Si based compound 4 dispersed in a region from the surface 2 of the sliding part 3 of the thrust bearing to a depth of 50 μm is subjected to process control at angles of 30° to 150° to the surface 2 of the sliding part 3, and hence the surface area of grains of the needle Mn-Si based compound 4 is mostly restricted in the brass ground. Thus, since the falling due to sliding is suppressed, seizure can be prevented without damaging the bearing surface 2 and the shaft surface during sliding.

    Abstract: PROBLEM TO BE SOLVED: To provide a sliding bearing excellent in anti-seizure property, which is used in a turbocharger of an internal combustion engine, and in which an inter-grain distance of an Mn-Si compound dispersed in a matrix of a copper alloy is controlled.
    SOLUTION: If the crystallized Mn-Si compound dispersed in the matrix of the copper alloy has an average inter-grain distance of 20-80 μm, a uniformly active state is achieved since the whole of the copper alloy matrix in the sliding surface of the sliding bearing is affected by a difference in a thermal expansion amount with the crystallized Mn-Si compound, and a non-metal sulfide film can be formed in an early stage on the surface of the copper alloy matrix. Therefore, sliding between a mating shaft surface and a metal surface can be prevented and the anti-seizure property of the sliding bearing can be improved.

    Abstract: PROBLEM TO BE SOLVED: To provide a copper-based sliding material which has excellent seize resistance by controlling a dispersed state of needle-shaped Mn-Si-based compounds crystallized in a brass structure.SOLUTION: In the copper-based sliding material 1 having the needle-shaped Mn-Si-based compounds 3 dispersed in the brass structure 2, 50% or more of the total number of the needle-shaped Mn-Si-based compounds 3 having a length in the long axis direction of 50 μm or more are composed of a plurality of small particles 4. Thereby, even if the needle-shaped Mn-Si-based compounds 3 fall off during sliding, the small particles 4 which constitute the needle-shaped Mn-Si-based compounds 3 may fall off. Thus, the frequency of falling off of the coarse needle-shaped Mn-Si-based compound 3, which damages a shaft and a bearing, is decreased. Therefore, seizure hardly occurs.
