Mechanical and physical properties. Instead alloys, however both materials can be attacked by corrosion which it definitely contributes to the depletion of our natural resources. The main objectives of this study were to observe the corrosion behavior of stainless steel 304 and Aluminum Alloys 6061 under variation of ph and to investigate the effect of ph variation on the surface and microstructure of stainless steel 304 and Aluminum Alloys 6061. This study was conducted by following the scopes of this project includes the sample preparation, cleaning procedure before and after test, exposure to actual condition, surface and microstructure observation using Scanning Electron Microscopy (SEM) and corrosion rate analysis by weight loss method. Under pH variation, there are three types medium of test used include acidic by Nitric Acid, alkaline by Sodium Hydroxide and Neutral by distilled water. Each sample undergoes environmental exposure for a week before the surface morphology investigation was conducted. From the experimental result during test day, there are changes in color medium of test (Nitric acid, Sodium hydroxide and distilled water) when testing both materials under variation of pH. The surface morphology of Stainless Steels and Aluminum Alloys had been observed using SEM for materials characterization. Corrosion rate was determined for all samples. It was found that Aluminum Alloy 6061 posses the highest rate of corrosion; 208.69mpy in acidic (HNO3) followed by alkaline (NaOH); 40.98mpy and lastly neutral (Distilled Water); 29.00mpy.For Stainless Steels 304, the highest corrosion rates occur in medium of Nitric acid which was 35.30 mpy while the lowest corrosion rates occur in medium of distilled water which was 2.05 mpy. The corrosion rate in medium of Sodium Hydroxide was about 7.22 mpy. Any features of corrosion failure give significant clue of the possible corrosion factor. This article details a proven approach to properly determining the effects of the pH variation and material types to the corrosion rate, and includes surface microstructure of the most common corrosion types, including crevice corrosion, pitting, and intergranular. In conclusion, pH variation influence the rate of corrosion. Because of passivation and high chromium contents, it forms a barrier or protective film on the surface and microstructure of AISI 304 thus decrease the corrosion rate compare to AA 6061. Hence, AISI 304 was proves to be the most protective sample and corrosion durable. Also, it may suggest that for engineering application under variation of pH, AISI 304 is highly recommended. |
