摘要:
为了系统研究铜合金涂层中Fe含量对其微观组织和力学性能的影响,采用自制铜合金粉末在6061铝合金上进行激光熔覆试验,即在6061铝合金表面熔覆了不同Fe含量的铜基复合熔覆层。试验结果显示,不同Fe含量的熔敷层组织从底层到表面分别为平面晶体、柱状晶、胞状晶和等轴晶;合金涂层由AlCuNi、AlNi和金属间化合物相组成(即:FeAl和Fe3Al)。研究表明,熔敷层硬度和耐磨性随着FeAl和Fe3Al相含量的增加而相应提高,当w(Fe)=15%时,熔敷层的耐磨性达到最佳值。
Abstract:
In order to study systematically the influence of iron content on microstructure and mechanical properties of Cu alloy coating,laser cladding experiment of self-made Cu alloy powder was carried out on 6061 Al alloy. The Cu-based composite cladding layer with different Fe content was clad on 6061 Al alloy,the microstructure of cladding layers was planar crystal,columnar crystal,cellular crystal,and equiaxed crystal respectively from the bottom to the surface. The phases of the alloy coatings were composed of AlCuNi,AlNi and intermetallic compounds(i.e. FeAl and Fe3Al). The study results indicated that the hardness and wear resistance were enhanced with the increase of FeAl and Fe3Al content,when the content of Fe was 15%,the wear resistance of the cladding layer has the optimum value.
