Plasma Chemical Oxidation - PCO®

Creation of ceramic-like coatings

The PCO ® technology, also known as SURA coat black and SURA coat white coating is a specially designed developed anodic oxidation process. It is based on the plasma-chemical principles and uses spark-discharge effects. These produce ceramic-like coatings on anodically contacted substrate materials of aluminium, titanium and magnesium alloys at high bath voltages in aqueous electrolyte systems.

These layers consist mostly of the oxide and hydroxide compounds of the substrate material and oxide compounds of the electrolyte components.
