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

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
