摘要 | In order to improve the homogeneity of spherical Fe-rich particles within the Cu-rich matrix, the Cu95Fe5 (wt%) immiscible composite coating has been produced by the combination of mechanical alloying and laser cladding. The results show that the milled composite powder presents a polygonal morphology and is mainly composed of face-centered-cubic (fcc)-Cu solid solution. The demixing or delimitation is eliminated in the immiscible composite coating produced by laser cladding and large amounts of spherical alpha-Fe particles are dispersed within the epsilon-Cu matrix as a result of liquid phase separation (LPS). The size of the Fe-rich particles measured is in radius of similar to 1.5 mu m, which is much smaller than the calculated critical radius (similar to 2.3 mu m), confirming that the alpha-Fe particles containing a supersaturated Cu are driven by the dominant mechanism of Marangoni motion. Compared to Brass, the immiscible composite coating exhibits the improved homogeneous microhardness (153HV(0.2)) and higher corrosion resistance, as well as a saturated magnetization of similar to 9.19 emu/g and low coercivity of similar to 9.25 Oe.
