| Abstract: |
| Naro brush electroplating technology was employed to repair the hole of diesel engine valve guide tube using n-Al2O3/Ni nanocomposite solution. The difficulties of plating for small diameter holes and uneven deposit were solved. The wear tests were carried out. The results showed that the nanocomposite solution displayed higher depositing rate than the conventional Quick-nickel solution. The thickness uniformity of the nanocomposite coating reached <0.01 mm. The technology provided successful experience for repairing the imported equipment |
