摘　　要：采用粉末注射成形技术制备了5wt%TiC/316L复合材料。利用人工神经网络预测注射参数,并设计理想的脱脂和烧结工艺。最佳注射参数为:注射温度156℃、注射压力70 MPa、注射时间2 s、保压压力37 MPa、保压时间4 s、模具温度37℃。选择三氯乙烯作为脱脂溶剂,最佳脱脂温度为55℃,脱脂时间8 h。在1375℃真空烧结45 min时,烧结试件力学性能最佳,其硬度、抗拉强度、摩擦系数分别达到288 HV、508 MPa、0.530。TiC/316L composites were prepared by powder injection molding. Using artificial neural networks to predict injection parameters and ideal degreasing and sintering processes was designed. The best injection parameters were as follows:injection temperature of 156 ℃, injection pressure of 70 MPa, injection time of 2 s, holding pressure 37 MPa, holding time of 4 s, and mold temperature of 37 ℃. Trichloroethylene was chosen as the degreasing solvent. The optimum degreasing temperature was 55℃ and the degreasing time was 8 hours. The mechanical properties of sintered specimensat 1375 ℃, are best when sintered in vacuum for 45 min. The specimen with hardness of 288 HV, tensile strength of 508 MPa and friction coefficient of 0.530 is obtained.
