摘要:
為了系統研究銅合金涂層中Fe含量對其微觀組織和力學性能的影響,采用自制銅合金粉末在6061鋁合金上進行激光熔覆試驗,即在6061鋁合金表面熔覆了不同Fe含量的銅基復合熔覆層。試驗結果顯示,不同Fe含量的熔敷層組織從底層到表面分別為平面晶體、柱狀晶、胞狀晶和等軸晶;合金涂層由AlCuNi、AlNi和金屬間化合物相組成(即:FeAl和Fe3Al)。研究表明,熔敷層硬度和耐磨性隨著FeAl和Fe3Al相含量的增加而相應提高,當w(Fe)=15%時,熔敷層的耐磨性達到最佳值。
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.
