AZ31/TiC surface composites were produced using Friction Stir Processing (FSP), with varying amounts of TiC particles. The microstructure and hardness measurements, as well as the evaluation of erosion wear resistance, were carried out on AZ31/TiC composites. X-ray diffraction tests were carried out to identify the phase composition. The presence of α-Mg and TiC phases was observed in all composites and no chemical interactions between the AZ31 matrix and TiC were observed at the interface. The AZ31 alloy is shown to have a hardness of 62 The AZ31 alloy reinforced with 15 vol% of TiC particles showed the highest resistance to cavitation with volume loss of 44 mm, while the AZ31 alloy showed the lowest resistance with volume loss of 142 mm for 15 min exposure time. HV ± 2 HV, whereas the AZ31/15 vol% of TiC composites is found to exhibit the highest hardness of 116 HV ± 5 HV.
采用搅拌摩擦加工（FSP）制备了含有不同含量TiC颗粒的AZ31/TiC表面复合材料。对AZ31/TiC复合材料进行了微观结构和硬度测量，以及耐冲蚀磨损性能评估。进行了X射线衍射测试以确定相组成。在所有复合材料中均观察到α-Mg相和TiC相的存在，且在界面处未观察到AZ31基体与TiC之间的化学相互作用。结果表明AZ31合金的硬度为62 HV±2 HV，而含有15体积% TiC颗粒增强的AZ31合金表现出最高的抗气蚀性能，在15分钟的暴露时间内体积损失为44立方毫米，相比之下，AZ31合金的抗气蚀性能最低，体积损失为142立方毫米。发现含有15体积% TiC的AZ31复合材料表现出最高硬度，为116 HV±5 HV。
