SLIDE MEMBER CAPABLE OF IMPROVING FATIGUE RESISTANCE CHARACTERISTIC AND NON-SEIZURE CHARACTERISTIC IN ADDITION TO THE SUPERIOR PRODUCTIVITY

摘要

PURPOSE: A slide member is provided to suppress the formation of Sn-Ni-Cu-based compound layer at the interference of a Sn-based overlay layer and a Ni-based intermediate layer by including copper at the sliding layer and the bottom layer of the Sn-based overlay layer.;CONSTITUTION: A slide member(11) includes a bearing alloy layer(13), a Ni-based intermediate layer(14) arranged on the bearing alloy layer, and a Sn-based overlay layer(15) arranged on the Ni-based intermediate layer. The Sn-based overlay layer includes at least one layer. A Sn-based sliding layer(15a) forming the Sn-based overlay layer includes Sn and 3 mass% or more of Cu. A Sn-based bottom layer(15b) forming the Sn-based overlay layer includes Sn and 8mass% or less of Cu. The thickness of the Sn-based bottom layer is 0.5um or more.;COPYRIGHT KIPO 2012
