摘要 利用循环伏安法测定了氢在钒基固溶体V3TiNi0.56Cr0.1贮氢合金中的扩散系数。氢的氧化峰峰值电流IP与扫描速度的平方根υ1/2之间有较好的线形关系,说明整个反应受氢原子的扩散控制。扩散系数为DH=9.8×10-8cm2/s。结果表明:钒基固溶体V3TiNi0.56Cr0.1贮氢合金电极的大电流放电性能较差。 The hydrogen diffusion coefficient in V-based solid solution alloy V_3TiNi_(0.56)Cr_(0.1) is determined by cyclic voltammetry. The cyclic voltammetry of V_3TiNi_(0.56)Cr_(0.1) electrode exhibites a good linear relationship between I_P and υ^(1/2),suggesting V_3TiNi_(0.56)Cr_(0.1) electrode reaction being controlled by diffusion process. The diffusion coefficient is found to be 9.8×10^(-8)cm^2/s. The results show that the large current discharge property of V-based solid solution alloy V_3TiNi_(0.56)Cr_(0.1) is poor.
