| 中文摘要: |
| 为了实现丝材连续镀金过程中镀金层厚度的可控性，研究了金盐浓度、镀液温度、阴极丝的移动速度对电流效率的影响，采用牛津的X-Sight能谱仪对镀金层断面进行能谱分析和镀金层确定，通过JSM-6460型扫描电子显微镜观察镀金层断面形貌、测定镀金层厚度。结果表明：金盐浓度对电流效率影响较小，电流效率与镀液温度和阴极丝移动速度有关；当温度确定时，阴极电流密度亦随之确定，镀金层厚度仅与阴极丝移动速度有关；镀液温度为45℃，阴极电流密度为2.9 A•dm-2，阴极丝移动速度为3.2m•min-1时，镀金层厚度为1.0μm。 |

| The influence of the component of the gold salt, the electroplating temperature and the speed rate of the wire cathode on the current efficiency were researched in order to control the thickness of the coat better. The composition of the fracture was analysed by Oxford X-Sight energy spectrometer and the patterns and the thickness of the fracture were determined by JSM-6460 scanning electronic microscope. The results of the tests indicate that the current efficiency is effected by the gold salt component little and by the electroplating temperature and the speed rate of the wire cathode heavy, and the thickness of the coat is related to the speed rate of the wire cathode only with the defined current density of the cathode while the electroplating temperature is defined. When the electroplating temperature is 45 degree centigrade, the cathode current density is 2.9 A•dm-2, the speed rate of the wire cathode is 3.2m•min-1, the thickness of the coat is 1.0μm. |
