PENGARUH VARIASI SUHU SINTERING ALUMUNIUM MATRIK YANG DIPERKUAT KARBON NANOTUBE TERHADAP NILAI KEKERASAN

Abstract

This study examines the effect of sintering temperature variations on density values and Vickers hardness values on Aluminum Carbon Nanotubes. Tests were conducted using five temperature variations, namely sintering 400°C, 500°C, 600°C, 700°C, and unsintered. The results showed that the 400°C sintering temperature variation produced higher hardness values than the 500°C, 600°C, 700°C, and unsintered sintering temperature variations. AlCNT specimens at a sintering temperature of 400°C have an average hardness value of 46.92 VHN, while at a sintering temperature of 500°C have an average hardness value of 30.48 VHN, while at a sintering temperature of 600°C have an average hardness value of 29.04 VHN, while at a sintering temperature of 700°C have an average hardness value of 26.17 VHN, while at a sintering temperature of 0°C have an average hardness value of 39.79 VHN. Therefore, it is found that the best sintering temperature variation for AlCNT specimens is 400°C for the application of sintering to aluminum carbon nanotubes. In addition, this research can be a reference for further researchers in developing manufacturing methods and characterization of aluminum reinforced with carbon nanotubes to obtain optimal results.
