Daftar Isi:
- Aluminum is widely used in the industry for its light weight, corrosion resistance and good heat conductivity and high electrical. Violence is not so high and a less attractive appearance needs to be fixed, one of which with a coat of aluminum with a Nickel electroplating process. This research aims to know the influence of voltage and time of Nickel plating on aluminum scrap casting. The specimen made from castings of optional with a size of 30 x 30 x 10 mm. Nickel coated aluminum with electroplating process with a voltage of 3, 4.5 and 6 volt. With the variation of time coating 5, 10 and 15 minutes. Once coated, micro hardness testing done by the method of testing the Vickers with a load of 10 gr and detained 10 s. test results indicate the presence of nickel plating hardness values increase with increasing voltage and time. Electric voltage 3 volts of 10.4%-15.9%, 4.5 volt voltage of 14.3%-4.62%, and 6-volt voltage of 24.8%-84.2%
