Abstract

It was shown through two experiments that submicron-size pits formed on the surfaces of a dense fused quartz substrate and a Y2O3-ZrO2 ceramic thin film that were coated with gold and then heat-treated in air at 1200 °C. The formation of the pits is believed to be caused by the positive capillary pressure (approximately 22 MPa) generated in the molten gold droplets (<1 μm in diameter) that were formed as the gold coating melted.
