Tailoring the performance of DLC coatings through interlayer engineering.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Diamond-like carbon (DLC) coatings have been widely studied for their exceptional hardness, low friction, and excellent wear and corrosion resistance, making them highly attractive for biomedical and industrial applications. However, their practical implementation is often hindered by internal stress and poor adhesion to metallic substrates. In this study, the effect of interlayers including plasma nitriding (PN), zirconium nitride (ZrN), and tantalum nitride (TaN) on the microstructure, wear behavior, and corrosion resistance of DLC coatings was investigated. FESEM images revealed a high density and uniformity of the DLC coatings in all three samples, with crack-free and pore-free surfaces. AFM analysis indicated that the ZrN + DLC and TaN + DLC samples, with surface roughness values of 3.42 nm and 3.31 nm respectively, exhibited smoother surfaces compared to the PN + DLC sample, which had a roughness of 42.34 nm. Wear testing showed that the TaN + DLC sample exhibited the lowest weight loss (8 mg) and wear rate (0.001901 mm³/N·m). Moreover, impedance curves indicated the highest corrosion resistance in the TaN + DLC sample. These findings demonstrate that the incorporation of ZrN and TaN interlayers significantly enhances the surface characteristics, particularly surface roughness and structural uniformity, along with the wear and corrosion resistance of DLC coatings.
