摘要: 采用微弧氧化技术对SiC体积分数分别为17vol%和55vol%的两种SiCp/Al复合材料进行处理。分析了两种材料微弧氧化膜的组织、形貌、相组成,测定了膜层的粗糙度、显微硬度、结合力,考察了膜层的耐磨和耐蚀性。结果表明:SiC的含量对SiCp/Al复合材料微弧氧化膜的表面形貌、粗糙度、相组成、结合力及摩擦磨损性能均有影响。17vol%SiCp/2009Al复合材料的微弧氧化膜较55vol%SiCp/6061Al复合材料更平整,微孔大小更均匀。55vol%SiCp/6061Al复合材料的微弧氧化膜的粗糙度(3.308 μm)比17vol%SiCp/2009Al复合材料(2.140 μm)大,表面熔融物堆积更多。两种材料的微弧氧化膜中均含有Al、Si、O、C、W等元素。55vol%SiCp/6061Al复合材料的微弧氧化膜中Mullite(SiO2-Al2O3)相、α-Al2O3相、β-Al2O3相较多。17vol%SiCp/2009Al复合材料的微弧氧化膜的结合(38.55 N)较55vol%SiCp/6061Al(11.5 N)复合材料好。55vol%SiCp/6061Al复合材料的微弧氧化膜摩擦系数较大,磨损较严重。微弧氧化处理能有效改善两种SiCp/Al复合材料的耐蚀性。Abstract: Two kinds of SiCp/Al composites with volume fraction of silicon carbide(17vol% and 55vol%) were treated by micro-arc oxidation. The microstructure, morphology, phase composition of micro-arc oxidation film on the two materials were analyzed. The roughness, microhardness, bonding force of films were measured. The wear and corrosion resistance of films were investigated. The results show that the content of SiC has an effect on the surface morphology, roughness, phase composition, bonding force and wear resistance of SiCp/Al composites. The micro-arc oxidation film of 17vol%SiCp/2009Al composite is flatter than the 55vol%SiCp/6061Al composite, and the pore size is more uniform. The micro-arc oxidation films of both materials contain elements such as Al, Si, O, C, and W. The roughness of the 55vol%SiCp/6061Al composite micro-arc oxidation film(3.308 μm) is larger than that of the 17vol%SiCp/2009Al composite (2.140 μm), and has more surface melt. The micro-arc oxidation film of 55vol%SiCp/6061Al composite has more mullite phase, α-Al2O3 phase and β-Al2O3 phase. The combination of micro-arc oxidation film and matrix of 17vol%SiCp/2009Al composite(38.55 N) is better than that of 55vol%SiCp/6061Al composite (11.5 N). The micro-arc oxidation film of 55vol%SiCp/6061Al composite has large friction coefficient and serious wear. The corrosion resistance of SiCp/Al composites is improved by micro-arc oxidation treatment.
