Wear-resistant mosaic block reinforced steel-based composite material, preparation method and application
The invention belongs to the technical field of metal-based wear-resistant composite materials, and discloses a wear-resistant mosaic block reinforced steel-based composite material, a preparation method and application, pretreated ZTA ceramic particles and an adhesive are uniformly mixed according to a certain proportion, a certain proportion of alloy powder is added, the mixture is uniformly mixed, and the mixture is loaded into a graphite mold for drying and curing; putting into a vacuum sintering furnace for presintering, and taking out a ceramic particle sintered preform with configuration after furnace cooling; placing in a casting mold cavity, and pouring molten metal for compounding treatment to obtain the wear-resistant composite inlaid block with the reinforced structural ceramic particles; after being ground, the multiple prepared embedded blocks are arranged and fixed in a casting mold cavity, high-temperature molten metal is poured in, and a wear-resistant composite casting is prepared through secondary compounding; and taking out the wear-resistant composite casting, and carrying out heat treatment to obtain the wear-resistant composite casting with excellent performance. The production process is simplified, the production cost is reduced, the waste of resources is reduced, the service life is prolonged, and the like.
本发明属于金属基耐磨复合材料技术领域，公开了一种耐磨镶嵌块增强钢铁基复合材料、制备方法及应用，预处理后的ZTA陶瓷颗粒与粘接剂按一定比例均匀混合，加入一定比例的合金粉末并混合均匀，装入石墨模具中进行干燥固化；放入真空烧结炉中预烧结，随炉冷却后取出具有构型的陶瓷颗粒烧结预制体；放置在铸型型腔中浇注金属液复合处理，得到具有结构陶瓷颗粒增强的耐磨复合镶嵌块；将制备出的多块镶嵌块打磨加工后，排列固定于铸型型腔，浇入高温金属液，二次复合制备出耐磨复合铸件；待耐磨复合铸件取出，并进行热处理，得到性能优异的耐磨复合铸件。本发明简化了生产工艺、降低生产成本、减少资源的浪费、提高使用寿命等。
