Problems solved by technology

[0007] The main technical problem to be solved by the present invention is that the lining plate materials used in various industries mainly include several single metal materials such as high manganese steel, multi-element low alloy steel, chromium series white cast iron, etc. The hardness decreases at high temperature and cannot resist the pressing of abrasive and scratching, the surface produces a lot of cutting wear and plastic deformation during use, low cycle fatigue, poor abrasive wear resistance, and poor toughness, easy to peel off and break, providing a nano-alumina reinforced wear-resistant liner preparation method

Abstract

The invention discloses a preparation method for a nano aluminum oxide reinforced highly wear-resistant liner plate and belongs to the technical field of metal material preparation. Cerium oxide in ceramic powder components is the oxide with the strongest activity among rare earth oxides, which can reinforce the interaction of atomic orbital between the ceramic powder and molecules of a coated base casting in a compound plating solution, so that the high-temperature resistance of the wear-resistant liner plate is improved. When the compound plating solution is used for dip-coating a substrateplate, alumina hydrate particles in the compound plating solution adsorb surrounding metal ions to be positively charged and migrate to the surface of the substrate plate continuously under the actionof electrostatic attraction. When the alumina hydrate particles are in contact with the surface of the substrate plate, a high density aluminum oxide membrane with ultrafine grain sizes can reduce the Akron abrasion volume dose of the wear-resistant liner plate, so that the binding force between metal ceramic powder and the substrate plate can be improved by means of the nano aluminum oxide particles. The nano aluminum oxide particles are unlikely to peel off and keep a high density, and are unlikely to wear, so that the wear resistance of the wear-resistant liner plate is improved and the wear-resistant liner plate has a wide application prospect.

Description

technical field [0001] The invention discloses a method for preparing a nano-alumina reinforced wear-resistant liner, which belongs to the technical field of metal material preparation. Background technique [0002] Wear-resistant linings refer to various wear-resistant linings processed from wear-resistant steel plates through cutting, coiling deformation, drilling and welding, such as conveyor linings, coal feeder bottom plates / cyclone separator inverted cones And liners, wear-resistant blades, etc., the wear-resistant life can be increased by more than 15 times than ordinary steel plates. [0003] Wear-resistant materials are a kind of special materials, which are mostly used in occasions with wear and tear, such as: mining machinery, construction machinery, powder equipment, mechanical parts that interact with materials such as soil, ore, rock, and cement; grain and oil processing, farming Harvesting and other agricultural machinery; many mechanical parts in water conse...
