| Abstract | ||
| Using α-brass (70-30) to prepare specimens with dimensions of 1 cm diameter and 2 cm length . XRF test was performed for specimens to ensure the chemical construction of used brass. After grinding, polishing, washing the specimens, they were weighted and immersed in different concentrations of acetic acid (0.5-2.5 M) for ten days. Determination of corrosion rate was calculated, moreover copper concentration in the solution provided estimation of copper release rate from the brass surface using AAS device. Optical microscopy test, the tensile test, and wear rate test were performed before and after immersing. This paper presents results of experimental study aimed to investigate effect of acetic acid on corrosion products of copper-based alloys at temperatures up to 100oC. It was found that the corrosion rate of brass was higher with increase in concentration of acetic acid up to 2.5 M. Also it increased with increasing temperature and exposure time. More corrosion rate caused more worse in mechanical properties. | ||
