Colour drift in decorative PVD: Why most defect reports get the root cause wrong
Two distinct physical mechanisms create colour in PVD coatings. Misidentifying which one is active in your process will send you chasing the
PVD Target Cooling: Direct or indirect?
PVD coating causes heat. Cooling can be done directly or indirectly. The table compares both methods.

Process Control in PVD Coating – Stable Reactive Sputtering with Speedflo and Optix
Why Process Control Is Essential in PVD In plasma and vacuum technology, precise process control is a key success factor. In reactive sputtering, instabilities occur when the gas flow rate reaches the range of stoichiometric film compositions. Without effective control, identical process parameters can produce very different outcomes – such as variations in reactive gas partial pressure, target voltage, or deposition rate. The result: inconsistent film quality, higher scrap r
