“…Aluminum is one type of non-ferrous metal that is most widely used in the world, especially in the automotive, aircraft industry, manufacturing industry, and household appliances, this is because aluminum has several advantages such as being lightweight, resistant to corrosion, cheap, and easy to be formed [1]. However, when compared to other commercial metals, aluminum has a relatively lower hardness and wear resistance [2,3].…”

Aluminum 6061 has the advantages such as good formability, corrosion resistance and lightweight, but it also has weaknesses, such as its hardness andwear resistance are relatively low, thus anodizing process is conducted to increase its hardness and wear resistance. The anodizing process can also produce a more attractive appearance and texture of metal. It alsocan increase the resistance of surface friction. The anodizing technique isa metal plating processbased on the formation of an aluminum oxide coating through controlled oxidation. The quality of the anodizing product is determined by the thicknesses of the coating formed. This study aimed to determine and analyze the mechanical properties and thicknesses of the coating on the surface of aluminum 6061 due to anodizing process. The method used in this research was a laboratory experimental method, with variations of the anodizing solution, voltage, and immersion time. The solutions used in this study were 100% 1M sulfuric acid, phosphorus acid, and nitric acid. The voltages used in this study were 15V and 30V, while the immersion time variation of the anodizing process was carried out at 10 minutes and 30 minutes. The mechanical properties of anodizing aluminum 6061 were tested using hardness and wear resistance tests. The data that had been obtained were analyzed using the descriptive analysis method. The results showed that the highest hardness rate was obtained in the treatment with the use of 100% H2SO4 anodizing solution, with a voltage of 15V, which was immersed for 30 minutes. The highest hardness reaching 106.47 HV was found in specimen number 2, with a wear resistance of 17153.09 m/g, and a coating thickness of 57.025 µm.

Purpose: This research is aimed to describe heat treatment process by using multistage artificial aging for Al-Cu alloy with Taguchi method in Minitab 16 to optimize the heat treatment parameters. This research conducted due to the applied of aluminium alloy in automotive industrial and aircraft industrial that has good properties for fabrication. Design/methodology/approach: Methodology that use in this paper is experimental design with statistical approach. Three controllable parameters were selected, they were temperature aging, holding time of aging, and the number of stages. The hardness value and impact value after multistage artificial aging were chosen as quality characteristics. The experiment was performed using orthogonal arrays of L9 (33). Findings: The finding that resulted in this research are the most significant parameters that affected hardness and toughness value of Al-Cu alloy against multistage artificial aging. The optimal hardness and toughness for Al-Cu alloy were obtained with heat treatment at temperature 200ºC, holding time for 6 hours, with two stages artificial aging. Research limitations/implications: The limitation that found in this research is even optimal level had been determined, it is unable to determine the true optimal value of each design parameters. Practical implications: This optimization process can be applied in manufacture process in industrial without spend expensive cost and time. Originality/value: According to research result, can be understood that by conducting these experiments, the impact value and the hardness value of Al-Cu alloy increase with multistage artificial aging treatment.
