Abstract:The infiltration mechanism, which has great significance for the quality control of electrieal contact material made from W-Cu, W-Ag alloys with high content of tungsten, has been studied. And a directive infiltration technology for improving the product quality and gaining a better economic benefit has been developed.
Key words: contact material W-Cu alloy W-Ag alloy infiltration mechanism infiltrant leakage black core
