| Abstract: |
| Based on the speciality of tubular parts interior chromium plating, three kinds of chromium electroplating bath were studied, they were standard bath, ordinary additive bath, self-made additive bath. Chromium coating plated by those bath were analyzed, measured deposition rate by weighing method, analyzed taper of chromium plating by magnetic film thickner, corrosion resistance and wear-resisting property of each chromium coating were tested, internal stress of each chromium coating were measured, characterization the chromium coating with SEM. The results show that the self-made additive is beneficial to increase deposition rate of chromiucoating and property, reduce taper. |
