چکیده
In this research, the effect of different additives on manufacturing of alumina - zirconia nanocomposites were investigated. The composites were produced from alumina and yittria stabilized zirconia nano powders by sinter forging method. Average particle size of primary alumina and zirconia powder were about 10 and 50 nm, respectively. The hard and soft agglomerates in primary powders were removed by ball milling. In order to prevent reagglomerating, different additives (PCAs) such as urea, ethanolamine, Anthraquinone, and glucose were used and their effects on green density were investigated. The effects of additives on microstructure and relative density of sintered samples were investigated too. The results show that 1000 ppm urea increased green density and improved microstructure, density, and hardness of sinter forged samples in comparison with other additivesکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
