氨基磺酸盐体系制备多孔镍

Preparation of Porous Nickel in Sulfamate Bath

采用氨基磺酸盐体系在碳骨架上制备了多孔镍。观察了多孔镍的表面形貌和断口形貌,并测试了多孔镍的孔隙率和压缩性能。结果表明:原始碳骨架的孔隙率为93.0%,经过电沉积之后孔隙率减小了6.0%~11.2%;氨基磺酸盐体系所得多孔镍的最高抗压强度是硫酸盐体系所得多孔镍的最高抗压强度的9.37倍;氨基磺酸盐体系所得多孔镍断口为三角形断口,断口镀层较厚且均匀,镀层中间未见裂纹。

Porous nickel was prepared on carbon skeleton in sulfamate bath.The surface morphology and fracture morphology of porous nickel were observed,and the porosity and compression property of porous nickel were tested.The results showed that the porosity of the original carbon skeleton was 93.0%,and it was decreased by 6.0%-11.2% after electrodeposition.The maximum compressive strength of porous nickel prepared in sulfamate bath was 9.37 times higher than that of the porous nickel prepared in sulfate bath.The porous nickel prepared in sulfamate bath exhibited triangular fracture,the coating was thick and uniform,and there was no cracks in the middle of the coating.
