【摘要】：鑒于傳統(tǒng)水溶液中電鑄鎳普遍存在的析氫問題以及離子液體這種新型介質(zhì)的巨大優(yōu)勢,系統(tǒng)地研究了在離子液體中溫度、電流密度對電鑄鎳層形貌和結(jié)構(gòu)的影響,并首次測定了離子液體中電鑄鎳件的抗拉強度和顯微硬度。結(jié)果表明:110~130℃是較理想的電鑄鎳溫度,升高溫度能明顯提高電鑄鎳層的結(jié)晶程度,并使晶粒的擇優(yōu)取向由(111)向(200)轉(zhuǎn)變;1 mA/cm~2是較理想的電流密度,隨電流密度的增大晶粒逐漸變小,結(jié)晶性能也隨之減弱;此外,與水溶液相比,離子液體中的電鑄鎳層有更高的抗拉強度和顯微硬度。
[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，
