ملخص المقالة :
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.
