Abstract
Abstract The present invention aims to provide a sliding member: to be operated under a high load and high sliding speed; having high impact resistance and high break-in property; to be highly resistant and stable under boundary lubricating conditions, and; to be engaged with the swash plate made of iron or aluminum in a swash plate type compressor. The sliding member of the present invention comprises: a base comprising an iron-based alloy, and; a bearing layer, consolidated to said base and formed by applying on said base a powder coating having a thickness not more than 0.5 mm, and then baking said coating, said powder consisting of an iron family element and an additive component which includes from 3 to 30% by weight of boron.
