| 中文摘要: |
| 针对某军用矩形电连接器镀金插孔出现表面发黑的现象,通过微观形貌观测、X 射线光电子能谱分析、显微红外光谱分析及气相色谱-质谱分析等表征分析手段,得出故障原因是插孔表面粘染了含胺基的有机物,有别于常见的镀金件因底层金属腐蚀引起变色。 |
| 英文摘要: |
| For the discoloring phenomenon of a military rectangular electrical connectors gold-plated surface, it was characterized by means of microstructure observation, X-ray photoelectron spectroscopy, infrared spectroscopy, gas chromatography and mass spectrometry, and figured out the surface stained with amine-containing organic compounds causing discoloration,unlike common discoloration for gold-plated pieces due to underlying metal corrosion. |
