采用粉末注射成形技术制备出SiC颗粒增强Cu基复合材料,研究了注射成形工艺参数对注射件和烧结件性能的影响。结果表明,通过优化整个工艺参数,可以避免试样缺陷的形成。当注射压力为120 MPa、注射温度为180℃、注射速度为40 m/s时,试样成形性能良好;提高溶剂脱脂温度有利于提高脱脂率;采用较低的升温速率脱脂和烧结时,能避免产生气泡和变形等缺陷。 SiC particle reinforced Cu matrix composites were prepared by powder injection molding. The effects of injection molding parameters on the properties of injection molded parts and sintered parts were studied. The results show that by optimizing the entire process parameters, the formation of sample defects can be avoided. When the injection pressure is 120 MPa, the injection temperature is 180 ℃ and the injection speed is 40 m / s, the formability of the sample is good. Increasing the degreasing temperature of the solvent is favorable for increasing the degreasing rate. When degreasing and sintering at a lower heating rate Avoid creating bubbles and deformation defects.
