Effect of hardness matching of aero spline sub-materials on wear performance.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
In engineering applications, wear and tear is a primary contributor to structural vibrations and noise. Excessive wear can lead to adverse effects such as chattering and instability, potentially culminating in catastrophic engineering failures. Thus, enhancing the surface wear resistance of structural components is an urgent necessity to ensure optimal drive train performance. This study investigates the hardness compatibility of commonly used hard spline sub-materials to elucidate the intrinsic damage behavior of these materials. The theoretical framework established here provides a foundation for selecting and optimizing hardness parameters in aerospace spline materials, a critical factor in their effective design. The materials analyzed include 9310 alloy steel, 15-5PH steel, 18CrNiMo, 32Cr3MoVA, and 40CrNiMoA. Results demonstrate that increasing the Hi/He ratio significantly reduces inner spline wear volume, thins the resulting oxide film, and shifts the dominant wear mechanism from abrasive to fatigue wear. The analysis reveals that total wear is minimized when the Hi/He ratio reaches 1.05.
