Daftar Isi:
- Aluminum was widely used in the industry because of its light weight, along with the increasing need for spare parts which has spurred the foundry industry locally to utilize the aluminum alloy scrap material to be melted again (re-melting). Although, nowadays many local industries remelting wheels scrap, but the resulting product had a highly roughness of material surface, so it is necessary to finish the process with surface treatment method of electroplating using nickel-chrome. This study aims to determine the effect of voltage and time of nickel-chrome plating on aluminum scrap casting products. During the nickel-chrome plating process, the voltage of 5, 7, 5, 9 volts and the time of 5, 10, 15 seconds were used. The results shown that the aluminum scrap of nickel-chrome plating roughness decreased along with the increasing of electrical voltage and time. The 5 volts of electrical voltage resulted in decrease of surface roughness by 13,53 – 37,2 %, 7,5 volts resulted 2,7% - 55,91 %, and 9 volts resulted 24,9% - 49,71 %. Furthermore, 5 seconds of surface coating time produced 19,14% - 42,9% of the decreasing of surface roughness, 10 seconds produced 8,9% - 50,4 % and 15 seconds produced 47,1% - 57,4 %. These results shown that nickel-chrome plating with fluctuations in voltage and time had an effect on the surface roughness.
