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.

This study describes the microstructure phase and the hardness value produced in metal casting with variations in metal mold temperature with the addition of Ti-B elements. gravity casting, a technique that relies solely on gravity, is used for casting metals. This objective of this study to determine the mechanical properties characterization of specimens using die casting molds by varying the mold temperature between 250°C, 350°C, 450°C and the addition of 0.05% Ti-B alloying elements. In addition, this research can determine the right temperature for metal casting by gravity casting method. The material used in this research is recycle piston Al-Si (series 4xxx). The results of hardness testing at a temperature of 250°C have produced 123.9 HVN. The microstructure of the Al-Si-TiB alloy material has dense grain boundaries. This is because the casting with the addition of the TiB element functions as a grain refiner and reduces porosity in the microstructure. So, the smaller the porosity, the stronger the hardness of the specimen or material. This is because at low mold temperatures, the metal casting process will freeze faster, resulting in higher hardness. In addition, the increasing temperature of the die casting mold has a tendency to change the eutectic structure of silicon to primary silicon.
