Electrodeposition of Ni-B and Ni-Co-B Alloys by Using Boric Acid as Boron Source

In this letter, the formation of electrodeposited Ni-B and Ni-Co-B alloys by using boric acid as boron source was demonstrated. The estimated thickness of the films was 5 m. By means of Cyclic voltammetry, X-ray diffractometry and energy dispersive X-ray spectroscopy analyzes, it was showed that Ni-B and Ni-Co-B alloys, with composition Ni 94 B 6 and Ni 75 Co 21 B 4 , can be easily formed onto glassy carbon when no complexing agents are employed in the electrodeposition bath. These results open the door to the production of electrodeposited boron-containing alloys by using boric acid as precursor due to its low cost and large-scale production.
