This study has examined the pulse electrodeposition of copper from a deep eutectic solvent. Pulse plating parameters were selected using methodologies originally developed for aqueous solutions, including constraints arising double layer charging and mass transport effects. Although could be deposited under nearly all conditions, in many instances only partial was observed current efficiencies ...
در این پایان نامه لایه های آلیاژی co/ru و چندلایه ای های co-ru/ru به روش الکتروانباشت از یک الکترولیت تک حمام حاوی سولفات کبالت، کلرید روتینیوم و کلرید آمونیوم تهیه شدند. اندازه گیری مغناطومقاومت نمونه های چندلایه ای حاکی از اثر amr بود و ویژگی gmr در آن ها مشاهده نشد. به همین منظور فیلم های آلیاژی ni/cu و چندلایه ای های ni-cu/cu به ترتیب با dc plating و two pulse plating (در مد g/p) از الکترول...
background: the entrance of toxic compounds into wastewater treatment plants (wwtps) can induce disorder in their biological units. therefore, it is necessary to determine the sources of toxic wastewaters. in this study, the toxicity of the wastewater of 3 metal plating industries was assessed using sequencing batch reactor (sbr) bacteria. methods: to obtain the 1-1000 ml/l concentrations, the ...
Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...
Background and purpose: Heavy metals such as chromium, nickel, and zinc are the most common contaminants found in the plating wastewater that cause environmental pollution due to non-biodegradability. This study investigated the removal of chromium, nickel, zinc and turbidity from wastewater of plating and galvanized industries by electrocoagulation technology. Material and methods: This study...
