Abstract
In this study, the decorative chromium coating process was applied to the gun body produced from Al7075 alloy, and the properties of the coating layer formed on the alloy surface were investigated in detail. The coating layer thicknesses formed as a result of zinc, copper, nickel and chrome plating and the change in the surface roughness as a result of the coating process were examined. The microstructure and surface morphology of coatings were investigated by means of a scanning electron microscope (SEM). Surface roughness of coated samples was determined by a contact profilometer (MarSurf 1 MAHR) at a high sensitivity setting. Obtained results show that the Zn, Cu, Ni and Cr coating layers on the Al7075 alloy surfaces was found to be mainly homogeneous. Coating thickness increased from 5 to 30 μm, while changing the coating type from Zn to Cr. As a result, decorative chrome coating was successfully applied to the Al7075 alloy using electrolytic coating method with lower cost and shorter time compared to the other coating methods.

Abstract
Bu çalışmada, Al7075 alaşımından üretilen tabanca gövdesine uygulanan dekoratif kaplama aşamaları incelenerek alaşım yüzeyinde oluşturulan kaplama tabakasının özellikleri araştırılmıştır. Dekoratif krom kaplama aşamaları olan çinko, bakır, nikel ve krom kaplama sonucu oluşan kaplama tabakası kalınlıkları ve kaplama işlemi sonucu yüzey pürüzlülüğündeki değişimler incelenmiştir. Kaplamaların mikroyapısı ve yüzey morfolojisi taramalı elektron mikroskobu (SEM) ile incelenmiştir. Kaplanmış numunelerin yüzey pürüzlülüğü, yüksek hassasiyet modunda test cihazı MarSurf 1 MAHR ile belirlenmiştir. Elde edilen sonuçlar, Al7075 alaşım yüzeyleri üzerindeki Zn, Cu, Ni ve Cr kaplama tabakalarının homojen olduğunu göstermiştir. Kaplama türü çinko kaplamadan krom kaplamaya değişirken, kaplama kalınlığı ise 5 - 30 μm arasında artmıştır. Sonuç olarak, tabanca gövdesinde kullanılan Al7075 alaşım yüzeyine dekoratif krom kaplama tabakası, diğer kaplama yöntemlerine kıyasla çok daha kısa sürede ve çok daha düşük maliyetli olan elektrolitik kaplama yöntemi kullanılarak sentezlenmiştir.
