Performance Optimization and Industrial Application Analysis of Silicon Carbide-Based Composite Ceramic Sandblasting Nozzle

摘要: 针对传统陶瓷喷砂嘴在极端工况下易脆断与制造成本高的问题，本文系统剖析了碳化硅与碳化硼复合体系的材料设计与性能优化路径。通过构建微观多相协同增韧机制，该复合陶瓷在保持高硬度的同时改善了断裂韧性，并实现了复杂流道结构的近净成型。工程应用跟踪表明，其在降低综合制造成本的同时可适配多种高强度冲击磨料，可为表面处理行业的降本增效提供参考，并为高附加值领域耐磨构件的开发提供潜在的材料选择。

Abstract: Aiming at the problems of brittle fracture and high manufacturing cost of traditional ceramic sandblasting nozzle under extreme working conditions, this paper systematically analyzes the material design and performance optimization path of silicon carbide and boron carbide composite system. By constructing a microscopic multiphase synergistic toughening mechanism, the composite ceramics improved fracture toughness while maintaining high hardness, and realized near-net molding of complex flow channel structure. Engineering application tracking shows that it can adapt to a variety of high-strength impact abrasives while reducing the comprehensive manufacturing cost, which can provide reference for reducing costs and increasing efficiency in the surface treatment industry and provide potential material selection for the development of wear-resistant components in high value-added fields.
