Silicon nitride and silicon carbide combined ceramic tube for aluminum alloy die casting and preparation method of silicon nitride and silicon carbide combined ceramic tube
The invention relates to the technical field of aluminum alloy die-casting forming, in particular to a silicon nitride and silicon carbide combined ceramic material pipe for aluminum alloy die-casting and a preparation method thereof.The silicon nitride and silicon carbide combined ceramic material pipe for aluminum alloy die-casting is annular, the annular wall is of an opening structure, and the material is silicon nitride and silicon carbide combined ceramic; the powder is prepared from 45-85 parts by weight of mixed powder, 3-10 parts by weight of a reinforcing agent and 15-40 parts by weight of a conditioning agent solution, the mixed powder is composed of monatomic silicon powder, silicon nitride powder and silicon carbide powder. Under the action of the in-situ SiTi2N4 reinforced phase, the material pipe has excellent wear resistance, thermal shock resistance and low thermal conductivity and can adapt to the service environment of an ultrahigh-pressure casting machine, the production efficiency of the high-pressure casting machine is greatly improved, heat loss is reduced due to reduction of the thermal conductivity of the ceramic material, the temperature control capacity of aluminum alloy fluid in the material pipe is enhanced, and the service life of the material pipe is prolonged. And the high performance and the stability of the product are ensured.
本发明涉及铝合金压铸成型技术领域，尤其涉及一种铝合金压铸用氮化硅结合碳化硅陶瓷料管及制备方法，一种铝合金压铸用氮化硅结合碳化硅陶瓷料管，管料为环状、环壁开口结构，材料为氮化硅结合碳化硅陶瓷，由45～85重量份的混合粉体、3～10重量份的增强剂和15～40重量份的调质剂溶液制得；混合粉体由单质硅粉体、氮化硅粉体和碳化硅粉体组成。在原位SiTi2N4增强相的作用下，料管具有优异的耐磨性能、抗热冲击性能、低热导率，能适应超高压铸造机的服役环境，大幅度提高高压铸造机的生产效率，陶瓷材料热导率的降低使得热量损耗减少，对料管内铝合金流体的温度控制能力增强，保证了产品的高性能与稳定性。
