در این تحقیق سنتز و ایجاد پوشش کامپوزیتی fe-tic با استفاده از کنستانتره ایلمنایت و فرایند پوشش دهی لیزری بر روی سطح فولاد ساده ی کربنی بررسی شد. دو ترکیب با نسبت مولی گرافیت به ایلمنایت 4 مول و 6 مول بررسی شد. نمونه ی با نسبت مولی 6 به مدت 100 ساعت آسیا کاری شد. مخلوط پودری با مقداری چسب مخلوط شده و به ضخامت 500 میکرون بر روی سطح فولاد aisi 1018 پیش نشانی شد. در ادامه عملیات لیزری بر روی سطح لا...
Powder injection melting (PIM) and material extrusion additive manufacturing (MEAM) are promising production technologies that allow us to obtain products from modern composite materials. These make it possible of complex shape ceramic materials, which is a non-trivial task. A highly filled polymer feedstock used as source in such technologies. In this work, study the structures properties samp...
The mysterious 21μm emission feature seen in sixteen C-rich proto-planetary nebulae (PPNe) remains unidentified since its discovery in 1989. Over a dozen of materials are suggested as the carrier candidates. In this work, we quantitatively investigate eight inorganic and one organic carrier candidates in terms of elemental abundance constraints, while previous studies mostly focus on their spec...
