Super wear-resistant nano coating of burr pressing roller

The utility model discloses a super wear-resistant nano coating of a burr pressing roller, the surface of the burr pressing roller is coated with a nano protective layer, the nano protective layer isa metal ceramic composite coating, and the metal ceramic composite coating comprises a nano bottom layer and a nano ceramic surface layer. And the nano bottom layer and the nano ceramic surface layerare sequentially sprayed from the bottom layer to the surface layer. The super wear-resistant nano coating of the burr pressing roller is provided with the wear-resistant and scratch-resistant nano coating composite material, the composite material has good physical performance and chemical stability, the binding capacity of the coating and a base material can be improved, mechanical load and impact resistance are both achieved, and the service life of the composite material is prolonged. The service cycle is prolonged from original 2 months to 68 months or above, the service cycle is greatlyprolonged compared with tha
