AI Technical Summary
Existing wear-resistant materials are prone to breakage and rapid wear under conditions of high drop, large particles and strong impact in mineral processing plants, and cannot meet the wear resistance and toughness requirements of equipment.
Alumina is used as the main raw material, combined with a mixture of niobium pentoxide, strontium oxide, lanthanum oxide and magnesium oxide as sintering aids, modified urea-formaldehyde resin microspheres, hafnium boride and tungsten disilicide as reinforcing and toughening phases, and wear-resistant ceramic liners are prepared through specific process steps. The carbide phase generated by the high-temperature pyrolysis of modified urea-formaldehyde resin microspheres forms a chemical bonding interface with the alumina matrix, which hinders crack propagation, and the thermal expansion gradient is adjusted by aluminum titanate to relieve thermal stress.
The prepared ceramic liner has good wear resistance and toughness, which can effectively prevent crack propagation, improve the hardness and impact resistance of the material, reduce the risk of cracking caused by thermal stress, and improve service life.
