摘　　要：以提高金属与塑料之间的结合强度为目标,对金属基体进行高能喷丸处理,使其表面自纳米化,并以高能喷丸和喷涂的工艺参数为试验变量,设计了正交试验方案,同时设计了压制成型模具并压制成型,最后采用垂直拉伸法对金属塑料复合材料的结合强度进行了测试,并研究了铸钢丸直径、喷丸压力、喷丸时间以及塑化温度对复合材料结合强度的影响规律,确定了使结合强度达到最佳的工艺参数组合。再运用数值拟合的方法,预测出结合强度最高的工艺参数组合,并对优化结果进行实验验证分析。结果表明,铸钢丸直径为4.96～5.04mm,喷丸压力为0.49～0.51MPa,喷丸时间为10.9～11.08min,塑化温度为278.2～282℃时制得的复合材料的结合强度最佳。In order to improve the bonding strength between metal and plastic,the high-energy shot peening of the metal substrate is carried out to make the surface self-nanochemical,and the orthogonal experimental scheme was designed based on the process parameters of high-energy shot peening and spraying. At the same time,the press forming mold was designed and pressed. Finally,the bonding strength of the metal matrix composite was tested by vertical stretching method,and the diameter of the cast steel shot,the shot peening pressure,the shot peening time and the plasticizing temperature were studied. The influence of the bonding strength determines the combination of process parameters when the bonding strength was optimized. Then,using the numerical fitting method,the combination of process parameters with the highest bonding strength was predicted,and the optimization results were verified by experiments. The results show that the diameter of the cast steel pellet is 4.96-5.04 mm,the shot peening pressure is 0.49-0.51 MPa,the shot peening time is 10.9-11.08 min,and the plasticizing temperature is 278.2-282℃. The composite material has the best bonding strength.
