“…Pengukur menggunakan teknik yang berbeda untuk mengukur ketebalan lapisan, tergantung pada jenis lapisan dan bahan yang diukur. Cara yang digunakan adalah dengan memancarkan gelombang ultrasonic untuk kemudian diubah menjadi indikator digital, sehingga mampu melakukan pengukuran dengan cepat dan tepat dengan pengukuran ketebalan yang presisi mencapai ± 0,1 mm [26] .…”

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

Anodizing is one way of coating oxidation on aluminum, which is carried out by anodic oxidation at room temperature with the help of an electric current so that a chemical reaction occurs so that a layer is produced that can protect the metal from the effects of corrosion. The objective of this study was to determine the characterization of variations in electric voltage on surface hardness in the anodizing aluminum series 6. Specimens were made with dimensions of 50 mm × 25 mm with a thickness of 10 mm, then the cleaning process was carried out with a solution of sodium carbonate (Na 2 CO 3 ) with a concentration of 50 gr/100 ml of reverse osmosis (RO) water. The etching, desmut, and anodizing processes were continued with a solution concentration of 400 ml of sulfuric acid (H 2 SO 4 ) and 600 ml of RO water. The electric voltage variables used were 20, 24, and 28-V with a current of 2 A and an immersion time of 10 min. The results of the highest hardness test on a variable voltage of 20-V with a Vickers hardness value of 59.117 VHN. This proves that anodizing treatment on the surface of aluminum material with a variable voltage of 20 V will produce a high Vickers hardness value. These results indicate that the toughness of the material on the anodized specimen is also affected by the magnitude of the electric voltage.
