Cu alaşımı yüzeyine GTA yöntemiyle alaşımlanan (Fe, MN) tabakasının mikroyapı ve sertlik üzerine etkisinin incelenmesi

Bu çalışmada, çok alaşımlı Cu yüzeyinde GTA yöntemi kullanılarak farklı mikro yapı ve sertliğe sahip katmanlar oluşturulmuştur. Numunelerin yüzeyinde 9 g ve 12 g toz emdirme miktarları, 115 A, 125 A ve 140 A akım şiddeti ve 25 V ile 28 V gerilim sabiteleri ile GTA yöntemi kullanılarak, yüzeyde alaşımlanmış bir katman meydana getirilmiştir. Bu katmanda nüfuz ettirilen toz miktarına bağlı olarak farklı sertlik değerleri tespit edilmiştir. Toz miktarının artışı ile sertlik değerinin de arttığı görülmüştür.

The investigation of effect on microstructure and hardness of alloyed (Fe, Mn) layer on surface of CU alloy by using GTA process

In this study, a layers which was acquired different microstructure and hardness were formed on copper based material surface by using GTA process. A new layer was produced on surfaces of specimens by using GTA process with 9 g and 12 g powder feed contents,115 A, 125 A and 140 A current, 25 V and 28 V voltage values, respectively. According to penetrated powder feed contents, different hardness values were determined in this layer. Hardness values were increased depend on rising powder feed contents.
