Improvement of AlTiN and AlCrN coatings with multicathode configuration
Multicathode configuration
is becoming very popular, and gains increased attention among the researchers and process engineers working in high power impulse magnetron sputtering in the Physical Vapour Deposition (PVD) coating industries.
