Abstract
To provide a thermal spray membrane contact material, contact member and contact part and an apparatus to which they are applied, showing excellent seizure resistance and wear resistance even under high surface pressure/low speed sliding, high speed/high temperature sliding, or high surface pressure/high speed sliding. In a bucket connecting apparatus connecting an arm and a bucket by a work implement connecting pin, the above-mentioned work implement connecting pin comprises a base material made of steel having an axis function and a contact surface formed of a thermal spray membrane contact material film-formed on the base material, said contact surface being placed at least on a supported surface site of the work implement connecting pin relative to a bracket and on a slipping contact surface with a work implement bushing, further, said thermal spray membrane contact material being composed of a Mo metal phase, or 10 vol % or more of a Mo metal phase and a metal phase and/or alloy phase containing one or more elements selected from the group consisting of Fe, Ni, Co, Cr, Cu and Zn.
