Abstract

Intermetallic materials exhibit desirable properties for many applications. They can be produced by traditional production techniques such as casting or powder metallurgy. In addition, they can be manufactured using some coatings techniques. Pack cementation technique is a very cheap, fast and simple operation to produce an intermetallic layer. 904L super austenitic stainless steel composed of high amounts Fe, Ni and Cr. It can be used in pulp and paper processing, some acid processing plants, cooling devices or oil refinery material. Its hardness is not high, and its usage temperature is low (<400 °C). To enhance these properties, aluminizing technique can be used. In the current study, 904 L super austenitic stainless steel was used as substrate material for the pack aluminizing process. The aluminizing process was applied at 675 °C for 2 and 4 h. After the aluminizing process, an aluminide layer formed on the 904L steel. The obtained aluminide layer thickness is about 19.2 and 290 µm for 2 and 4 h aluminizing process, respectively. The Aluminide layer is composed of FeAl2, Fe2Al5, FeAl and Al5FeNi phases in both aluminized samples. The formation of aluminide phases provided higher hardness on the surface of 904L stainless steel compared to untreated 904L.

Özet

İntermetalik malzemeler birçok uygulama için arzu edilen özellikler sergilemektedirler. Döküm veya toz metalurjisi gibi geleneksel üretim teknikleri ile üretilebilirler. Ayrıca bazı kaplama teknikleri kullanılarak üretilebilirler. Kutu sementasyon tekniği, intermetalik bir tabaka oluşturmak için çok ucuz, hızlı ve basit bir işlemdir. 904L süper östenitik paslanmaz çelik yüksek miktarda Fe, Ni ve Cr' den oluşmaktadır. Kağıt hamuru ve kağıt işlemede, bazı asit işleme tesislerinde, soğutma cihazlarında veya petrol rafinerisi malzemelerinde kullanılabilmektedir. Sertliği yüksek değildir ve kullanım sıcaklığı düşüktür (<400 °C). Bu özellikleri geliştirmek için alüminyumlama tekniği kullanılabilir. Mevcut çalışmada, kutu aluminyumlama işlemi için altlık malzemesi olarak 904 L süper östenitik paslanmaz çelik kullanılmıştır. Alüminize etme işlemi 675 °C'de 2 ve 4 saat süreyle uygulanmıştır. Alüminize etme işleminden sonra 904L çeliği üzerinde bir alüminid tabakası oluşmuştur. Elde edilen alüminid tabaka kalınlığı, 2 ve 4 saatlik alüminize işlemi için sırasıyla yaklaşık 19.2 ve 290 µm'dir. Alüminid tabakası, her iki alüminyumlanmış numunede FeAl2, Fe2Al5, FeAl ve Al5FeNi fazlarından oluşmaktadır. Alüminid fazlarının oluşumu, 904L paslanmaz çeliğin işlem görmemiş haline kıyasla yüzeyinde daha yüksek sertlik sağlamıştır.
