Aimed at the preparation of bimetallic composites by using a liquid-liquid compound casting method with a sound interface, this study focused on the interface evolution with an increase in the pouring time interval. The results revealed that the melt mixing occurred when the pouring interval was 3 s. The transition zone appeared at the interface when the pouring interval was 10 s, and a good metallurgical bond was obtained. When the pouring interval was 20 s, a discontinuous oxide layer appeared at the interface. The oxide layer gap formed a channel for the transport of the SiC particles.
针对采用具有良好界面的液-液复合铸造法制备双金属复合材料，本研究聚焦于随着浇注时间间隔增加时的界面演变。结果表明，当浇注间隔为3秒时发生熔体混合。当浇注间隔为10秒时，界面处出现过渡区，并获得了良好的冶金结合。当浇注间隔为20秒时，界面处出现不连续的氧化层。氧化层间隙形成了SiC颗粒传输的通道。
