Experimental study on Fe-Ni alloy electrodeposition in a vacuum

abstractFe-Ni alloy electrodeposition in a vacuum was carried out in this paper, and Fe-Ni alloy deposits was prepared on the stainless substrate based on the vacuum environment which could isolate oxygen, remove hydrogen and make the electrolyte boiling. The effects of the current density on the Fe content, the phase, the preferred orientation and the micro-hardness of the Fe-Ni alloy deposits prepared in the vacuum were analyzed by comparison with the traditional electrodepositing process. The results showed that the vacuum electrodeposition technique can significantly increase the Fe content and diffraction peak intensity of the alloy deposits. Simultaneously the vacuum electrodeposition can usually improve the micro-hardness of the electrodeposited Fe-Ni alloy. It has been proved that the microstructure and property of the deposit mentioned above were all influenced by the current density.
