▎ 摘　　要

NOVELTY - A movable sealing ring material comprises a substrate and a coating adhered on an outer end portion of the substrate. The coating comprises 20-30 pts. wt., preferably 25 pts. wt. zirconia, 10-20 pts. wt., preferably 15 pts. wt. hydroxyapatite, 30-50 pts. wt., preferably 40 pts. wt. titanium dioxide, 20-30 pts. wt., preferably 25 pts. wt. graphene and 10-20 pts. wt., preferably 15 pts. wt. nano alumina. USE - Movable sealing ring material (claimed). ADVANTAGE - The movable sealing ring material can be firmly attached, and is prepared by rapid and simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of movable sealing ring material, which involves polishing the substrate, sandblasting the polished substrate in a sandblasting machine, spraying mixture (A) on one end of the substrate to form coating, cooling, molding, and polishing. The mixture (A) is obtained by mixing zirconia, hydroxyapatite, titanium dioxide, graphene and nano alumina for 10-20 minutes, and heating the resultant mixture in a heating furnace at 300-400 degrees C to a molten state.
