| Abstract: |
| 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. |
