KARAKTERISASI LAPISAN OKSIDA HASIL ANODIZING PADA ALUMINIUM DENGAN VARIABEL WAKTU PENCELUPAN

Anodizing is an electrolytic coating process that converts aluminum into oxide. The anodizing widely used in the manufacturing industry, especially automotive components. Its utilization has benefits such as resistance to scratches, ease of maintenance, and added decorative value. purpose this study was determine effect time variations on hardness thickness oxide layer 6xxx series processes. variation immersion 20, 30, 40 minutes, with electric current 2 amps a voltage 24 volts. After that, dyeing sealing carried out. tests out included testing (Vickers) (coating gauge). results highest test 112.9 VHN were obtained at average 5.07 m. It can be said amount spent how hard gets thick it metal.
