【摘要】：鉴于传统水溶液中电铸镍普遍存在的析氢问题以及离子液体这种新型介质的巨大优势,系统地研究了在离子液体中温度、电流密度对电铸镍层形貌和结构的影响,并首次测定了离子液体中电铸镍件的抗拉强度和显微硬度。结果表明:110~130℃是较理想的电铸镍温度,升高温度能明显提高电铸镍层的结晶程度,并使晶粒的择优取向由(111)向(200)转变;1 mA/cm~2是较理想的电流密度,随电流密度的增大晶粒逐渐变小,结晶性能也随之减弱;此外,与水溶液相比,离子液体中的电铸镍层有更高的抗拉强度和显微硬度。
[Abstract]:In view of the widespread hydrogen evolution problem of electroformed nickel in conventional aqueous solution and the great advantage of ionic liquid as a new medium, the effects of temperature and current density on the morphology and structure of electroformed nickel layer were systematically studied. The tensile strength and microhardness of electroformed nickel in ionic liquids were determined for the first time. The results show that 1: 110 鈩，
