DIN ISO 6751 AH, Hardened
Ejector Pin with the cylindrical head and DLC-coating. Ejector pins, and other components, coated with DLC.
DLC: These are non-crystalline (amorphous) hydrocarbon layers which are produced in a PACVD
(Plasma Activated Chemical Vapour Deposition) process and which contain 50% to 70% carbon alignment, similar to that of diamonds. Both layer types consist of graphite based anti-friction layers, not conventional hard material coatings. This means that in comparison with a purely hard material coating they display approximately 50% better flexibility.
