Abstract
An apparatus comprising a plurality of sliding members, at least one of the sliding members being a self-lubricating-function sliding member characterized by containing a precursor compound which produces a solid-lubricating compound during sliding by reacting with an atmosphere in which the sliding member is used or a component of a material with which the sliding member is in sliding contact.
Claims21
An apparatus, comprising a plurality of sliding members, wherein at least one of said sliding members comprises a matrix material and a precursor material dispersed in at least a surface region of said matrix material, said precursor material providing a solid lubricant material, different from said precursor material, on a sliding surface of the sliding member by chemical reaction induced by sliding.
An apparatus comprising a plurality of sliding members, wherein at least one of said sliding members has a solid lubricant on a sliding surface thereof, said solid lubricant being produced by chemically reacting a precursor material, different from said solid lubricant and contained in the sliding member, with another material upon application of heat and pressure caused by sliding.
