Abstract
The invention belongs to the technical field of nanotechnology, and particularly relates to an aluminum dam roller with a wear-resistant nano metal ceramic coating capable of resisting roughness reduction. The aluminum dam roller with the abrasion-resistant nanometer metal ceramic coating capable of resisting roughness reduction comprises a roller body, the roller body is a cylinder, the surface of the roller body is coated with the abrasion-resistant nanometer metal ceramic coating, and the nanometer metal ceramic coating sequentially comprises a base layer, a bonding layer and a functional layer from inside to outside. The functional layer is a nano tungsten carbide coating; and the roller body mounting shafts are positioned at two ends of the roller body. According to the wear-resistant nano metal ceramic coating provided by the invention, the roughness of the surface can be better maintained, and the friction coefficient of the surface of the dam roller is increased. And nano-scale tungsten carbide can be effectively coated on the surface of the dam roller.
