| Summary: | Kajian mengenai elektrosaduran ke atas substrat gegelang piston sebenar sebuah enjin kecil dua lejang telah dilakukan. Substrat telah dielektrosadur dengan Ni tulen, Ni-SiC, Ni-Cg(grafit)-SiC dan Ni-P-Cg(grafit)-SiC. Suhu saduran ditetapkan pada suhu bilik, nilai pH dilaraskan dari 3.6 ke 4.0 dan ketumpatan arus ditetapkan pada 30 mA/cm2.
Electroplating of piston rings substrate of a small two stroke utility engine was carried out. The substrates were electroplated with pure Ni, Ni-SiC, Ni-Cg(graphite)-SiC, and Ni- P-Cg(graphite)-SiC. The plating temperature was fixed at room temperature, pH was regulated from 3.6 to 4.0, and current density was fixed at 30 mA/cm2. |
