本文研究了SiC颗粒增强Al基复合材料的干滑动磨损性能，研究了增强量、载荷、滑动速度和滑动距离对搅拌铸造Al-SiC-Gr混杂复合材料、Al-Gr和Al-SiC复合材料的影响。参数研究表明，混杂复合材料的磨损有增加的趋势超过%增强7.5%，其值分别为0.0242 g，0.0228 g和0.0234 g在3%，7.5%和10%的增强。Al-Gr复合材料的相应值为0.0254 g、0.0240 g和0.0242 g，Al-SiC复合材料的相应值为0.0307 g、0.0254 g和0.0221 g，这清楚地表明混杂复合材料具有更好的磨损特性。速度的增加减少了磨损，载荷或滑动距离的增加或两者的增加增加了磨损。统计分析揭示了载荷、滑动速度和滑动距离之间的相互作用。(C)2010爱思唯尔有限公司版权所有。
This investigation studies the dry sliding wear behaviour of Al matrix composites reinforced with Grand SiC particulate up to 10%, to study the effect of % reinforcement, load, sliding speed and sliding distance on stir cast Al-SiC-Gr hybrid composites, Al-Gr and Al-SiC composites. Parametric studies indicate that the wear of hybrid composites has a tendency to increase beyond% reinforcement of 7.5% as its values are 0.0242 g, 0.0228 g and 0.0234 g respectively at 3%, 7.5% and 10% reinforcement. The corresponding values are 0.0254 g, 0.0240 g and 0.0242 g in Al-Gr composites and 0.0307 g, 0.0254 g and 0.0221 g in Al-SiC composites, clearly indicating that hybrid composites exhibit better wear characteristics. Increase of speed reduces wear and increase of either load or sliding distance or both increases wear. Statistical analysis has revealed interactions among load, sliding speed and sliding distance in composites with Gr particulates. (C) 2010 Elsevier Ltd. All rights reserved.
