Neutrosophic method for evaluating DLC coatings under dry weathering conditions

Abstract

This study aims to develop a Neutrosophic Method to evaluate diamond-like carbon (DLC) coatings under dry erosion conditions. A comprehensive evaluation of the performance of these coatings is presented, using a dry erosion rig specifically designed for this investigation. The performance of various DLC coatings was investigated, including hydrogenated amorphous carbon (a-C:H), silicon-doped amorphous carbon (a-C:H:Si) and tungsten-doped amorphous carbon (a-C:H:W). Tests were performed using 250 μm silica sand particles at an impact velocity of 15 m/s and a 90 degree angle. The results reveal significant differences in erosion resistance between the various types of DLC coatings, as well as the crucial influence of the substrate material on their performance. This approach will not only allow a more rigorous evaluation of the erosion properties of DLC coatings, but also establish a reproducible methodology that can be applied in future studies. In this way, it will contribute to the understanding of how to optimize these coatings in industrial applications where wear resistance is essential, thus enhancing their use in various technological applications. The development of the Neutrosophic Method promises to be a significant advance in the characterization and improvement of DLC coatings under dry erosion conditions.
