Plasma-deposited dlc multilayer coatings: Saint GobainRecent Research Landscape

Surface degradation and mechanical failure in harsh environments drive up replacement costs. Engineering discrete dielectric and split diamond-like carbon layer sequences mitigates delamination and enhances scratch resistance.

What technical problems is Saint Gobain addressing in Plasma-deposited dlc multilayer coatings?

Thermal degradation of scratch resistance

(1)evidences

Excessive compressive stress in diamond-like carbon films leads to poor adhesion and spontaneous delamination. Reducing this stress prevents coating failure and enables thicker protective layers.

High temperature oxidative degradation

(1)evidences

Excessive compressive stress in diamond-like carbon films causes spontaneous delamination and poor substrate adhesion. Reducing this stress prevents coating failure and extends component lifespan under mechanical load.
