研究了热挤压纯镁及其1wt%纳米碳化硅增强复合材料的磨损性能。磨损试验是在干燥和油滑条件下进行的，采用球面上平面式结构。结果表明，纳米复合材料具有较低的磨损量，这主要是由于纳米颗粒对硬度的提高和颗粒的细化所致。随着滑动速度的增加，磨损量逐渐减小，然后开始上升到一个临界值以上。随着磨损温度从25℃提高到190℃，纳米复合材料的磨损量减小。
This paper presents the wear properties of hot-extruded pure Mg and its composite reinforced with 1 wt.% SiC nanoparticles. Wear tests were performed under dry and oil sliding conditions using ball-on-flat configuration. It was found that the nanocomposites show much lower wear loss mainly due to hardness improvement caused by the nanoparticles and grain refinement. The wear loss gradually decreases as the sliding speed increases and then it begin to rise beyond a critical value. With the wear temperature improves from 25 to 190 °C, wear loss of nanocomposites reduces.
