▎ 摘　　要

NOVELTY - Self-lubricating ceramic material comprises ceramic base material and composite powder, where composite powder comprises 7.5-15.0 pts. wt. graphene-like structure molybdenum disulfide, 2.5-5.0 pts. wt. silver, 5-10 pts. wt. barium sulfate, and 35-70 pts. wt. crystal powder. USE - Self-lubricating ceramic material. ADVANTAGE - The self-lubricating ceramic material utilizes silver to diffuse from the inside of the coating to the surface to form a continuous lubricating film, which inhibit oxidation of molybdenum, improve nano hardness and elastic modulus of the material, and improve mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing self-lubricating ceramic material, which involves: (A) taking alumina micropowder and molybdenum powder into a planetary ball mill, and then adding anhydrous ethanol to wet ball milling for 12-24 hours and then drying to obtain a matrix powder; (B) tiling base powder in a selective laser sintering molding apparatus to perform 3D printing into a spatially ordered honeycomb structural material to obtain a ceramic base material; (C) taking molybdenum disulfide powder, sodium cholate in deionized water, ultrasonic dispersion, centrifugation, collecting and drying, to obtain graphene-like structure molybdenum disulfide; (D) taking calcium fluoride, cesium fluoride, mixed into a mixer, and then sintering at 1100-1200 degrees C for 30-40 minutes, cooling and grinding for 3-5h, to obtain eutectic powder; (E) taking graphene-like structure molybdenum disulfide, silver, barium sulfate, eutectic powder, and mixing it into a mixer to obtain a composite powder, and uniformly coating the composite powder on the surface of the ceramic base material; and (F) placing in a vacuum hot press sintering machine, heating to 1200-1300/oC at 20 degrees C/ minutes, helding at 20-30 Mega Pascals for 20-30 minutes, cooling to room temperature and taking out to obtain self-lubricating ceramic material.
