| Abstract Scope |
Several boriding processes producing a hard boride layer on suitable transition metals are very slow and cost-prohibitive. Thick boride layers can provide high resistance to wear, oxidation. Among the boriding processes, electrochemical boriding has been shown to achieve very thick and uniform boride layers at very fast rates without causing much environmental pollution. We used this technique to synthesize thick boride layers on several refractory metals including Hf, V, Zr, Ti, Re, Ta, Nb, Cr, Mo, W, and Ni at 10000C for a duration of 1-hour. Borided metals have been characterized using structural and mechanical methods. While borided Ni exhibited the largest thickness (i.e., 480 µm), borided Hf had a thickness of about 3.5µm. In terms of hardness, the highest hardness was measured on borided Mo which was around 40 GPa. The others had lower hardness values while the hardness of base refractory metals ranged from 5 to 8 GPa. |
