<P>PROBLEM TO BE SOLVED: To provide a sprayed-coating sliding material, a sliding member and sliding parts having excellent seizure resistance and wear resistance even under high-specific-pressure/low-speed sliding, high-speed/high-temperature sliding and high-specific-pressure/high-speed sliding, and to provide an apparatus to which these are applied. <P>SOLUTION: For example, in a bucket coupling device 9B where an arm 5 and a bucket 6 are connected by a working machine connecting pin 26, the working machine connecting pin 26 is constituted so that it has a base material 27 made of steel with a shaft function and a sliding surface 29 formed of the sprayed-coating sliding material 28 deposited on the base material 27 and this sliding surface 29 is provided on at least the portion of the surface to be supported of the working machine connecting pin 26 with respect to a bracket 6a and on the sliding contact surface with respect to a working-machine bush 30, respectively, wherein the sprayed-coating sliding material 28 is composed of Mo metal phase or metal phase and/or alloy phase containing ≥10 vol.% Mo metal phase and one or more elements among Fe, Ni, Co, Cr, Cu and Zn. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
