Investigation on the Effect of Corrosion on Mechanical Properties of Al 6061 & Al 7075

Abstract

In this thesis we are going to analyze the Aluminium alloys of series Al 6061 and AL 7075 by conducting mechanical tests. And the mechanical properties differences are spotted in the corrosion test. ASTM Corrosion Testing is provided, including the ASTM B117 Salt Spray Test. For the initial work pieces and later hardness test is carried out for testing the hardness of the materials which is better. Here even the corrosion timing is also varied according to the 10, 20, 30 hours for the sample pieces. After that we have verified with the hardness test machine for the strength of the material using Rockwell tester machine. 3 samples have been taken for each alloy, so totally 6 samples have been tested and the results are verified.
