Behavior of oxide film on void surface of the diffusion-welded interface has been investigated with Auger electron spectroscopy, SEM and EPMA. Results obtained are summarized as follows.
1.The oxide film of aluminum on the void surface did not disappear during welding. However, the oxide film of copper, iron and SUS 304 stainless steel disappeared, forming lumps of oxide on the void surface owing to spheroidizing of the oxide film, wheres the lumps of oxide was not observed on the free surface heated in a vacuum. On the other hand, the oxide film of titanium disappeared without forming lumps of oxide.
2. Disappearance of the oxide film of copper, iron, SUS 304 stainless steel and titanium was owing to diffusion of the oxide film into the base metal.
