تثبیت لجن به عنوان بخش مهمی از مدیریت لجن حاصل از تصفیه خانه های فاضلاب همواره مورد نظر و بررسی دست اند در کاران و محققین صنعت آب و فاضلاب می باشد. با توجه به نتایج حاصل از روش های مختلف ارائه شده در چند دهه ی گذشته و نتایج عملکردی حاصل از آنها در موارد مختلف مورد استفاده، همچنان تلاش می گردد راهکار جدیدی جهت ارتقا سیستم های صنعتی مربوطه ارائه گردد. در این تحقیق بر اساس نتایج مطالعات اولیه در خ...
In this study, Ni-Mo nanocrystalline alloys were prepared on steel substrates by electrodeposition method from citrate-ammonia bath by applying current densities 30, 60 and 100 mA/cm2. Results indicated that the obtained coatings were uniform and compact. Moreover, molybdenum content in the alloy and current efficiency decreased with increasing electrodeposition current density. X-ray diff...
due to lack of knowledge management system in the organization of technical and vocational university of iran (tvuni) and losing good employees because of retirement and substitution causes huge amount of costs to replace the similar expertise. there is no any suitable system in the tvuni to store, to document, and to distribute knowledge. based on the university’s features such as it has diffe...
n this paper a finite element model has been proposed for evaluation of primary and secondary current density values on the cathode surface in nickel electroplating operation of a revolving part. In addition, the capability of presented electroplating simulation has been investigated in order to describe the electroplated thickness of the nickel sulfate solution. Nickel electroplating experi...
