Abstract

This study were investigated the effect of SiC amount and milling time on microstructure, density and hardness in the aluminum composites produced by mechanical milling. In the study, aluminum composites were mechanical milling at different times (30, 60, 90 and 120 min), adding SiC in different amounts (5%, 10%, 15% and 20%). A high chromium steel balls with a diameter of 6 mm, a ratio of 10:1 ball-powder and 2% stearic acid were used as milling component in the production of composites in a vibrating mill. The production of composite powders was carried out in an argon atmosphere. The composite powders produced were characterized using scanning electron microscopy, EDS analysis, optical microscope and powder size analyzer. As a result, it was observed that as the amount of added SiC and milling time increased, the powder size decreased and the hardness values increased. In addition, as the amount of added SiC increased, the densities of aluminum composites increased.

Özet

Bu çalışmada, mekanik öğütme ile üretilen alüminyum kompozitlerde SiC miktarının ve öğütme süresinin mikro yapı, yoğunluk ve sertlik üzerine etkisi incelenmiştir. Çalışma kapsamında alüminyum kompozitler, farklı miktarlarda (%5, %10, %15 ve %20) SiC ilave edilerek farklı sürelerde (30, 60, 90 ve 120 dak) mekanik öğütülmüştür. Titreşimli değirmende yapılan kompozitlerin üretiminde öğütme elemanı olarak 6 mm çapında yüksek kromlu çelik bilya, 10:1 bilya-toz oranı ve %2 stearik asit (işlem kontrol kimyasalı) kullanılmıştır. Kompozit tozların üretimi argon ortamında yapılmıştır. Üretilen kompozit tozlar tarama elektron mikroskobu, EDAX analizleri, optik mikroskop ve toz boyut analizörü kullanılarak karakterize edilmiştir. Yapılan çalışmalar sonucunda, ilave edilen SiC miktarı ve öğütme süresi arttıkça toz boyutunda azalma görülürken, sertlik değerlerinde artış görülmektedir. Bununla birlikte ilave edilen SiC miktarı arttıkça da alüminyum kompozitlerin yoğunlukları artmaktadır.
