Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

Surface and Interface Analysis, Volume 58, Issue 4, Page 246-261, April 2026.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.
