Gradient diamond/molybdenum disulfide composite self-lubricating anti-attrition engineering ceramic coating and preparation method thereof
The invention discloses a gradient diamond/molybdenum disulfide composite self-lubricating anti-attrition engineering ceramic coating and a preparation method thereof, and belongs to the technical field of full-ceramic self-lubricating anti-attrition coatings, and the coating comprises a multi-stage size progressive diamond coating and a molybdenum disulfide coating from the surface of an engineering ceramic substrate to the outside in sequence; each stage of progressive diamond coating comprises a micron diamond coating, a fine grain diamond coating and a nano diamond coating, and a molybdenum disulfide coating is deposited on each diamond coating; the deposited diamond coating is prepared by adopting a hot filament chemical vapor deposition method, the molybdenum disulfide film covering the diamond coating is prepared by adopting a direct current magnetron sputtering method, and molybdenum disulfide in the composite coating reacts with nano-diamond and is converted into onion-shaped carbon under certain conditions, so that the hardness and the lubricating property of the composite coating are improved, and friction and abrasion are reduced; the composite coating prepared through the method is more stable in binding force and adhesive force, and the service life of a machine is prolonged.
