NOVELTY - Solid lubricating ball bearing is claimed. The ball surface has a plasma sprayed chromium carbide-nickel-chromium-graphene coating having a thickness of 20-30 m. USE - Used as solid lubricating ball bearing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for spraying chromium carbide-nickel-chromium-graphene on solid lubricating ball bearing comprising mixing is carrying out using a planetary ball mill and centrifugal spray granulator will coating powder, (i) balling chromium carbide and nickel-chromium on a planetary ball mill to no longer precipitate, (ii) adding graphene into reaction mixture of step (i) to continue milling for at least 10 minutes, and (iii) stopping the ball mill reaction system of step (ii) before 5 minutes, then adding organic binder ball mill to obtain suspension, and (iv) spray-granulating the suspension obtained in step (iii) to obtain chromium carbide-nickel-chromium-graphene agglomerated particles.
