▎ 摘  要

NOVELTY - A multi-element composite texture oriented sliding friction pair comprises a main portion whose friction working surface is provided with uniformly distributed micro-pits and micro-bump. The partial micro-pits are adhered with solid lubricant. The solid lubricant is nano-scale solid lubricating material comprising 10-15 wt.% polyimide, 54-60 wt.% nano molybdenum disulfide, 0-10 wt.% carbon nanotubes, 0-10 wt.% graphene, 0-10 wt.% fullerene, and 0-5 wt.% adhesive. USE - Multi-element composite texture oriented sliding friction pair (claimed). ADVANTAGE - The multi-element composite texture oriented sliding friction pair effectively inhibits the lathe guide rail creeping phenomenon at low speed heavy load condition, effectively lubricates the rail, and has excellent friction-reducing anti-sticking effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for processing method of multi-element composite texture oriented sliding friction pair, which involves (1) pretreating substrate surface, (2) fabricating the composite micro-texture on the surface of the substrate by the combination of laser micro-texturing technology and laser hair-forming technology, providing micro-pits and micro-convex portion, (3) uniformly mixing solid lubricating material comprising 10-15 wt.% polyimide, 54-60 wt.% nano molybdenum disulfide, 0-10 wt.% carbon nanotubes, 0-10 wt.% graphene, 0-10 wt.% fullerene, and 0-5 wt.% adhesive, and activating the nanocomposite solid lubricating material, (4) masking without filling solid lubricant, (5) precoating the nanocomposite solid lubricant without covering the micro-pits, (6) rolling on the surface of the substrate, (7) using mold on a surface of the substrate filled with solid lubricant portion for partitioning, pressure maintaining, heating and curing processes, heating at 250-280 degrees C and at 7.5-8 MPa for 10-30 minutes, and (8) surface treating the substrate.
