INVESTIGATION OF THE RELATIONSHIP BETWEEN ETCHING DURATION AND SURFACE ROUGHNESS IN CHEMICAL MACHINING OF AA5754 AND AA7075 ALLOYS
Öz
In this study, surface roughness (Ra) and chemical wear rate changes were investigated in AA5754 and AA7075 aluminium alloys, which are widely used in industry, by using two different chemical etchants (A: HF, HCl, HNO3, H2O) (B: HF, H2O2, H2O) at different times. It is aimed to investigate the effect of the chemical solutions used on the surface properties of these materials. For both alloys, the highest surface roughness increase was obtained at 20 min etching time in B solution, while the highest chemical etching rate value was obtained at 10 min etching time in B solution. It was seen that chemical etching method is an effective method for etching aluminium surfaces and the structures and pore sizes formed on the samples can be controlled with the processing times.

AA5754 VE AA7075 ALAŞIMLARININ KİMYASAL AŞINDIRMA İLE İŞLENMESİNDE AŞINDIRMA SÜRESİ İLE YÜZEY PÜRÜZLÜLÜĞÜ İLİŞKİSİNİN İNCELENMESİ
Öz
Bu çalışmada endüstride yaygın olarak kullanılan AA5754 ve AA7075 alüminyum alaşımlarında iki farklı kimyasal dağlayıcı (A: HF, HCl, HNO3, H2O) (B: HF, H2O2, H2O) kullanılarak farklı sürelerde yüzey pürüzlülüğü (Ra) ve kimyasal aşınma hızı değişimi incelenmiştir. Kullanılan kimyasal çözeltilerin bu malzemelerin yüzey özellikleri üzerindeki etkinin incelenmesi amaçlanmıştır. Her iki alaşım için de en yüksek yüzey pürüzlülüğü artışı B çözeltisi içerisinde 20 dk aşındırma süresinde elde edilirken, en yüksek kimyasal aşınma hızı değeri B çözeltisi içerisinde 10 dk aşındırma süresinde elde edilmiştir. Kimyasal aşındırma metodunun alüminyum yüzeylerin aşındırılmasında etkili bir yöntem olduğu ve işleme süreleri ile numuneler üzerinde oluşan yapıların ve gözenek boyutlarının kontrol edilebileceği görülmüştür.
