【 摘 要 】

This study investigates the effect of saccharin addition on nickel deposits. Coating substrates with nickel is carried out through electroplating. This method involves Watts bath, 0, 1, 3, and 5 g/L saccharin, and a current density of 6 A/dm2. The electroplating process lasts for 20 minutes at 50°C. The plated substrate is a Steel Plate Cold Rolled Coil (SPCC). The deposits attached to the SPCC surface is characterized by a Scanning Electron Microscope (SEM) to observe the structural changes of the deposits and an X-Ray Diffraction (XRD) to calculate their grain size. The results show that, first, nickel deposits without saccharin addition has a pyramidal and crystal polyhedral structure while those with saccharin reflect a globular structure and colonial patterns. Secondly, the addition of 5g/L saccharin produces the smallest grain, 17.39 nm.
