（１）电沉积法电沉积法常被用来进行涂层或制备独立的结构。Ｅｒｂ等人首先将此法用于制备大块纳米金属材料，实验表明用传统的或稍加改性的电镀池和电镀条件可以制得晶粒尺寸为１１ｎｍ的纳米晶镍材料。形成电沉积电镀池所需基本组分是阳极、阴极、电解质和直流电源。获得纳 (1) Electrodeposition Electrodeposition is often used to coat or prepare individual structures. Erb and others first used this method for the preparation of bulk metallic nanomaterials. Experiments show that nanocrystalline nickel with a grain size of 11 nm can be prepared by traditional or slightly modified plating bath and plating conditions. The basic components required to form the electrodeposited plating bath are the anode, cathode, electrolyte, and DC power source. Get satisfied
