利用金相显微镜(OM)、扫描电子显微镜(SEM)和能谱分析仪(EDS)等分析研究了6063铝合金表面点状凸起物的表面形貌及成分.结果表明,这种点状凸起物主要是由大量聚集的碳化硅颗粒以及少量的游离硅组成,碳化硅颗粒硬度较大,不易加工,从而造成铝合金表面异常.

The morphology and composition of protrusions on 6063 aluminum alloy surface were researched by means of OM,SEM and EDS.The results show that the protrusions are composed of silicon carbide particle aggregation as well as little free silicon.Additionally,silicon carbide particles are very harder,so they are not easy to be processed. Thereby,the protrusions are formed on the aluminum alloy surface during the process.
