Abstract :
An aircraft is a transportation tool that is sensitive to be error and
damage. Safe flight operations start from aircraft maintenance that is guarenteed
and in accordance with procedures.
One type of metal used on aircraft is aluminium. Aluminium is a light
weight metal. Aluminium and its alloys have good corrosion resistance.
The results showed an anxiation of 7075-T651 material with the of current
using 1.5A 5% sulfuric acid mixture and anodizing time for 20 minutes got
weight reduction of 7,932 mpy. In 1,5 speciment, 10% sulfuric acid mixture and
anodizing time for 20 minutes experienced a weight reduction of 5.108 mpy, and
at 1,5A 20% sulfuric acid mixture obtained the smallest corrosion result as 2.280
mpy.
