Bu çalışmada, Cu-Cr toz metal (T/M) elektrot kullanımının elektro erozyon ile işleme (EEİ) performans çıktılarından işparçası işleme hızı (İİH), elektrot aşınma hızı (EAH), işlenmiş yüzeyin ortalama ve azami yüzey pürüzlülükleri (Ra ve Rz) ve işparçası yüzey katman kalınlıklarına etkileri deneysel olarak incelenmiştir. Farklı toz karıştırma oranları, sıkıştırma basınçları ve sinterleme sıcaklıklarında elde edilen Cu-Cr T/M elektrotlar SAE 1040 çeliğinin işlenmesinde kullanılmıştır. Analizler, elektrot malzemesinin işparçası yüzeyinde katman halinde alaşımlandığını ve karıştırma oranı, sıkıştırma basıncı ve sinterleme sıcaklığının EEİ performans çıktılarını etkilediğini göstermiştir.


Anahtar kelimeler


EEİ, T/M elektrot, Cu tozu, Cr tozu, karıştırma oranı, sıkıştırma basıncı, sinterleme sıcaklığı
