| Abstract | ||
| The effect of annealing process on corrosion resistance for aluminum (2024-T3) alloy is investigated. Samples of this alloy had been manufactured with dimensions (1.5*1.5*0.3) cm according to ASTM specifications. The annealing process applied by heating the metal in three deferent times; 270°C for two hours, 400°C for half hour and 350°C for one hour. After that the X-Ray Diffraction test has been done in order to know the phases resulted. The electrochemical corrosion test has been done by fixing the potential of the cell and changing it, the potential is chosen depending on open circle and comparing it with the standard metal potential of electrochemical series then adding 100 volt to show the cathode and anode behavior of metal, it had been found that the corrosion average resistance affected by temperature degree and time of the process, it had been noticed that increasing annealing temperature the corrosion resistance of alloy decreased, specially at 400°C, the heat treatment at the temperature 270°C was the best. | ||
