    摘要:

    在CaCl2 熔鹽中,以鈦精礦為陰極,電解制備了鈦鐵合金,并對產(chǎn)物進行了XRD和SEM檢測。對比不同溫度下電解產(chǎn)物的結(jié)果表明,溫度對擴散合金化過程影響顯著,不同溫度下電解產(chǎn)物的物相和結(jié)構(gòu)有明顯不同。850 ℃下電解的最終產(chǎn)物是顆粒大小為1 μm的TiFe2和Ti離散球型結(jié)構(gòu),而900 ℃下電解的最終產(chǎn)物是顆粒大小為3 μm的TiFe空間網(wǎng)狀結(jié)構(gòu)

    Abstract:

    In the CaCl2 molten salt, TiFe alloy was prepared by electroanalysis using titanium concentrate as the cathode. XRD and SEM analyses of products were performed. The electrolytic products at different temperatures were compared. Results show that the temperature has significant effects on diffused alloying process, and the phases and structures of electrolytic products are different. At 850 oC, the final electrolytic product is the TiFe2 and Ti discrete ball-type structure with the particle size of 1 μm, while at 900 oC the final product is the TiFe space net structure with the particle size of 3 μm
