Bu çalışmada Mg alaşımlarının kullanım alanlarını desteklemek amacıyla yeni bir yöntem ile kaplama işlemi yapılmıştır. AZ91 Mg alaşımı ile hazırlanan numuneler saf Si tozu içerisinde farklı sıcaklıklarda bekletilmiştir. Mg-Si faz diyagramı esas alınarak sıcaklıklar 400°C, 450°C ve 500°C olarak belirlenmiştir. Numuneler belirlenen sıcaklıklarda 2, 4 ve 6 saat bekletilmiştir. Bu aşamada yüzeyde Mg-Si arasında yeni bir fazın oluşması sağlanmıştır. Yüzeyde oluşan kaplama SEM, EDX ve sertlik testleri ile incelenmiştir. Sonuç olarak AZ91 alaşımına uygulanan kaplama işlemi ile 500°C/6 saat şartlarında yaklaşık 20 µm bir kaplama tabakası oluşmuştur. EDX analizinde fazın ve geçiş bölgelerinin elementel durumları incelenmiştir. Sertlik testi Vickers türünde uygulanmıştır. AZ91 alaşımının kaplamasız numunesine göre sertlik yaklaşık %90 artış göstermiştir. Böylece Mg alaşımlarında yüzeyde fazların oluştuğu kaplama yöntemleri uygulanabilir sonucuna varılmıştır.

In this study, a new method of coating was carried out in order to support the usage areas of Mg alloys. Samples prepared with AZ91 Mg alloy were kept in pure Si powder at different temperatures. Based on the Mg-Si phase diagram, temperatures were determined as 400°C, 450°C and 500°C. The samples were kept at the determined temperatures for 2, 4 and 6 hours. At this stage, a new phase was formed between Mg-Si on the surface. The coating formed on the surface was examined by SEM, EDX and hardness tests. As a result, with the coating process applied to the AZ91 alloy, a coating layer of approximately 20 µm was formed at 500°C/6 hours. Elemental states of the phase and transition zones were investigated in EDX analysis. Hardness test was applied in Vickers type. Compared to the uncoated sample of the AZ91 alloy, the hardness increased by about 90%. Thus, it was concluded that coating methods in which phases form on the surface can be applied in Mg alloys.
