Background

Medical CT scanners and X-ray tubes are core equipment in modern diagnostics. Their critical component — the rotating anode target — must operate reliably under high temperature, high vacuum, and intense radiation. Refractory metal (W, Mo) / graphite composite targets are the preferred solution due to their high melting points and excellent thermal dissipation.

Research

Composite Target Fabrication

  • Powder metallurgy fabrication of W/Mo-graphite composite targets
