Abstract

Brass is a mixture of copper and zinc. Brass is very easy to shape into various shapes, brass is mostly used for ship applications, one of which is the propeller, the propeller is usually damaged in the form of corrosion or hit by a hard object so that it bends or breaks at the tip of the propeller leaf. The electroplating process is one of the metal coating methods. The coating method is influenced by several parameters including: current strength, electrode distance, current distribution, coating time, concentration level of the electrolyte solution and others. The process of heat treatment (Hardening) is a process carried out to increase the hardness of the material. Hardening at a temperature of 650o C for 6 hours with the highest hardness value obtained by water quenching media of 101.78 HV (12, 67%) with a base material hardness of 90.34 HV. The results of the Vickers hardness test after the nickel-chrome electroplating process with a voltage variation of 1.5, 3, and 4.5 volts and a time of 5, 10, and 15 minutes, with a loading of 100 gf indentation time of 10 seconds with the highest hardness value obtained at a voltage of 4 ,5 volts and 15 minutes of 254.82 HV for nickel and 261.95 HV for nickel and 261.95 HV. The results of the thickness test after the nickel-chrome electroplating process based on the results of the Vickers test with the highest hardness value on nickel obtained a thickness of 70.90833 m and chrome at 99.5483 m. with a loading of 100 gf indentation time of 10 seconds with the highest hardness value obtained at a voltage of 4.5 volts and a time of 15 minutes of 254.82 HV for nickel and chrome of 261.95 HV of 261.95 HV. The results of the thickness test after the nickel-chrome electroplating process based on the results of the Vickers test with the highest hardness value on nickel obtained a thickness of 70.90833 m and chrome at 99.5483 m. with a loading of 100 gf indentation time of 10 seconds with the highest hardness value obtained at a voltage of 4.5 volts and a time of 15 minutes of 254.82 HV for nickel and chrome of 261.95 HV of 261.95 HV. The results of the thickness test after the nickel-chrome electroplating process based on the results of the Vickers test with the highest hardness value on nickel obtained a thickness of 70.90833 m and chrome at 99.5483 m.
