IAD – Ion assisted deposition

IAD | PIAD

During ion or plasma assisted deposition with electron beam evaporation (EBE), the process is enhanced by assisting ions or plasma. This upgrade increases the kinetic energy of condensing particles through momentum transfer. The IAD modification allows 3photon engineers to increase the density of the coating, effectively suppressing the primary disadvantages of traditional electron beam evaporation (EBE), such as limited process stability, repeatability, and the sensitivity of the manufactured coating to environmental changes. 3photon engineers have mastered the IAD/PIAD process and can produce highly complex multi-layer coatings.

  • Main advantages
  • Disadvantages
  • Dense layers and high environmental stability of the coating
  • Stress compensated coatings with optimized process parameters
  • Cost effective – deposition rates are close to EBE technology
  • Higher coating stress (tensions) limits substrate materials (e.g., IAD/PIAD cannot be used when applying coating on soft and sensitive materials)
