Abstract

This study aims to determine the effect of time variation in the anodizing process on the hardness, roughness and micro structure on the aluminum 1000 series. The specimens used in the process of anodizing aluminum 1000 series with a length of 80 mm, a width of 30 mm thickness 2.5 mm. The process is done, among others, the process of cleaning with a solution of sodium hydroxide, the process of etching with a solution of caustic soda and desmutt with a solution of nitric acid. Then do the anodizing process with a solution of H2SO4 time variation of 15 minutes, 30 minutes and 45 minutes at a current of 6 amperes 12 volts. After anodizing, made the process of dyeing and sealing using a liquid distilled water. The results obtained thickness of the oxide layer on the specimen variation 15 minutes at 10 µm, 30 min of 12 µm and 45 minutes by 14 µm. The results of hardness testing on the specimen variation time 15 minutes by 173,09 VHN, 30 minutes of 219,35 VHN and 45 minutes of 267,45 VHN. The results of testing the roughness on the specimen variation 15 minutes of 1,503 µm, 30 minutes of 1,589 µm and 45 minutes of 2,054 µm.
