چکیده مقاله :
رویکردهای پایدار در بازیافت مواد، کلیدی برای کاهش اثرات زیست محیطی فرایندهای تولید بهشمار میآیند. در این پژوهش، از برادههای تولید شده در ماشینکاری بهعنوان منبعی ارزشمند برای بازیافت استفاده شده است، که نهتنها کاهش پسماند، بلکه دستیابی به فرایندهای تولید مقرونبهصرفهتر و سازگار با محیطزیست را ممکن میسازد. از این طریق، تولید پودر برای روشهای نوین ساخت مانند سینترینگ پلاسمای جرقهای بهعنوان جایگزینی کارآمد و دوستدار محیطزیست برای روشهای سنتی ماشینکاری معرفی شده است. در این تحقیق با استفاده از فولاد CK45، چرخهای بسته برای بازیافت مواد ایجاد شدهاست، که در آن برادههای ماشینکاری مجدداً به نمونهای با لک تبدیل و قطعات تحت آزمونهای، سختیسنجی و تحلیل XRD قرار گرفتهاند. نتایج نشان میدهد که روش مبتنی بر بازیافت و متالورژی پودر نهتنها خواص مکانیکی برجستهای نظیر افزایش 30 واحدی سختی را ارائه میدهند بلکه نسبت به ماشینکاری سنتی، ضمن کاهش مخاطرات محیطزیستی، امکان تولید قطعاتی با ویژگیهای پیشرفته را فراهم میآورد. این دستاوردها چشماندازی جدید برای صنایع حساسی، مانند هوافضا و خودرو ارائه میدهد، که در آن کاهش اثرات محیطزیستی و افزایش کارایی، همگام با توسعه فناوریهای پایدار محقق میشود.
Sustainable approaches to material recycling are crucial for reducing the environmental footprint of manufacturing processes. In this study, machining chips are utilized as a valuable resource for recycling, thereby enabling both waste reduction and the development of more cost-effective and environmentally sustainable production processes. Through this method, powder production for advanced manufacturing techniques such as Spark Plasma Sintering (SPS) is proposed as an efficient and environmentally sustainable alternative to conventional machining methods. In this research, a closed-loop recycling process was established using CK45 steel, where machining chips were successfully converted into powder feedstock and consolidated into bulk specimens. These specimens were subjected to hardness testing and X-ray diffraction (XRD) analysis. The results demonstrate that this method not only enhances mechanical properties, including an increase of approximately 30 hardness units, but also provides measurable environmental advantages compared to traditional machining. The application of Spark Plasma Sintering facilitates the fabrication of components with advanced performance characteristics while reducing material waste and associated environmental risks. These findings provide a new perspective for critical industries, such as aerospace and automotive, where environmental impact reduction and efficiency enhancement are achieved in parallel with the advancement of sustainable technologies.
