NOVELTY - Self-lubricating composite material comprises nickel powder, aluminum powder, molybdenum powder, niobium powder, tungsten sulfide powder and nano-graphene powder, where the nickel powder, aluminum powder, molybdenum powder and niobium powder are used in mol ratio of 48:50:1:1. USE - Self-lubricating composite material. ADVANTAGE - The self-lubricating composite material is prepared in a convenient manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a self-lubricating composite material, which involves: (A) mixing nickel powder, aluminum powder, molybdenum powder, niobium powder and tungsten sulfide powder to obtain mixed powder; (B) adding nano-graphene powder to the mixed powder; and (C) processing the mixture in a graphite mold in the vacuum condition to obtain self-lubricating composite material.
