为了改进钒基固溶体贮氢材料的性能,采用超声搅拌辅助铸造法制备新型钒基固溶体贮氢材料V3Ti Ni0.56Co0.1Al0.2,并进行物相组成、显微组织、吸放氢性能和耐腐蚀性能的测试与分析。结果表明,该新型钒基固溶体贮氢材料由V基固溶体相和少量的Ti Ni相、Ti2Ni相组成,具有较佳吸放氢性能和耐腐蚀性能,室温最大吸氢量为1.781%、室温放氢平台压力为0.46 MPa,腐蚀电位较V3Ti Ni0.56正移709 m V。 In order to improve the performance of the vanadium-based solid solution hydrogen storage material, a novel vanadium-based solid solution hydrogen storage material V3Ti Ni0.56Co0.1Al0.2 was prepared by ultrasonic stirring assisted casting method. The phase composition, microstructure, hydrogen absorption and desorption properties Corrosion testing and analysis. The results show that the new vanadium-based solid solution hydrogen storage material consists of a V-based solid solution phase and a small amount of Ti Ni phase and Ti2Ni phase, has better hydrogen absorption and desorption performance and corrosion resistance. The maximum hydrogen absorption capacity at room temperature is 1.781% Hydrogen platform pressure of 0.46 MPa, corrosion potential than V3Ti Ni0.56 positive shift 709 mV.
