Optimization

  1. Improve the thermodynamic stability of tungsten copper alloy (increase electrode potential);
  2. Reduce the anode activity:
  3. Reduce the alloy cathode active phase of adaptation cathode control corrosion, non-passivated metal:
  4. Form the dense amorphous protective film on the surface of alloy, such as add Cu, P and alloy elements in steel.
