EFFECTS OF CARBOXYLIC ACID ADDITIVE ON HARD ANODIZING OF AL7075 ALUMINUM ALLOY

Year 2025, Volume: 13 Issue: 3, 1013 - 1022, 30.09.2025

Abstract

The effect of adding organic acid on the hard-anodizing coating on AA7075 aluminum alloy was investigated. Five different acid mixtures as electrolytes (Sulfuric acid (SA) + Acetic acid (AA), Sulfuric acid (SA) + Pyruvic acid (PA), Sulfuric acid (SA) + Malonic acid (MA), Sulfuric acid (SA) + Tartaric acid (TA), Sulfuric acid (SA) + Citric acid (CA)) were used as electrolysis bath. Scanning electron microscopy (SEM) analysis, EDS and elementary distribution analyzes were performed on the material surfaces after anodic oxidation, and Fourier Transform Infrared Spectroscopy (FTIR) analyzes were performed to determine the functional groups and molecular structures formed on the surfaces. As a result of the application, the highest coating thickness value was measured as 129.5 µm for tartaric acid. Fourier Transform Infrared Spectroscopy (FTIR) analysis generally shows that amorphous alumina contains Al-O bonds, Al-O-Al bonds and Al-OH bonds. The highest hardness value of 420 HV was obtained as a result of anodic oxidation by adding tartaric acid into a sulfuric acid bath

Abstract

Al7075 alüminyum alaşımının sert eloksal kaplamasına organik asit ilavesinin etkisi araştırılmıştır. Elektrolit olarak beş farklı asit karışımı (Sülfürik asit (SA) + Asetik asit (AA), Sülfürik asit (SA) + Pirüvik asit (PA), Sülfürik asit (SA) + Malonik asit (MA), Sülfürik asit (SA) + Tartarik asit (TA), Sülfürik asit (SA) + Sitrik asit (CA)) elektroliz banyosu olarak kullanıldı. Malzeme yüzeylerinde anodik oksidasyon sonrası taramalı elektron mikroskobu (SEM) analizi, EDS ve elementer dağılım analizleri, yüzeylerde oluşan fonksiyonel grupların ve moleküler yapıların belirlenmesi amacıyla Fourier Dönüşümü Kızılötesi Spektroskopi (FTIR) analizleri yapıldı. Uygulama sonucunda en yüksek kaplama kalınlığı değeri tartarik asit için 129,5 µm olarak ölçülmüştür. Fourier Dönüşümü Kızılötesi Spektroskopisi (FTIR) analizi genel olarak amorf alüminanın Al-O bağları, Al-O-Al bağları ve Al-OH bağları içerdiğini göstermiştir. En yüksek sertlik değeri 420 HV ile Sülfürik asit (SA) + Tartarik asit (TA) elektroliz banyosu ile elde edilmiştir.
