BEARING FOR INTERNAL COMBUSTION ENGINES

摘要

A bearing for an internal combustion engine may include a steel support layer. A coating layer containing a Cu alloy may be laid over the steel support layer. A Ni-based anti-diffusion barrier layer may be laid over the coating layer, and an anti-friction layer containing a matrix of Sn—Zn and Zn precipitates may be laid over the anti-diffusion barrier layer.
