چکیده مقاله :
در این مقاله، تأثیر سرعت چرخش ابزار بر روی خواص مکانیکی و خوردگی اتصال تیتانیوم خالص تجاری و آلیاژ آلومینیوم 5083، به روش همزن اصطکاکی، بررسی شده است. ابتدا با جوشکاری‌های مقدماتی محدوده پارامترهای لازم برای دستیابی به اتصال مناسب بدست آمده و سپس با تغییر سرعت چرخش ابزار، خواص مکانیکی و خوردگی نواحی متأثر از حرارت، ناحیة جوش و سطح مقطع جوش به کمک آزمون پلاریزاسیون تافل و روش طیف‌نگاری امپدانس الکتروشیمیایی، بررسی شده و نتایج حاصل مورد مقایسه قرار گرفته است. نتایج نشان می‌دهد که رفتار خوردگی در اتصالات، از سرعت چرخش ابزار تأثیر پذیر بوده و نواحی جوش و متأثر از حرارت، مقاومت در برابر خوردگی ضعیف‌تری نسبت به فلزات پایه داشته‌اند.
In this paper, the effect of tool rotation speed on the mechanical properties and corrosion behavior on dissimilar joints Friction Stir Welds between 5083 Aluminium alloy and pure Titanium is investigated. At first, with primary welding parameters range necessary to achieve suitable connection obtained and then by changing tool rotation speed, mechanical and corrosion properties of heat affected zones, welding zones and cross section zones, by using polarization Tafel test and Electrochemical Impedance Spectroscopy was investigated and the result were compared. the result indicates that corrosion behavior of connections, is impressionable of the tool rotation speed and welding zone and heat affected zones have weaker corrosion resistance compared to the base metals.
