    Influence of carbon variation on the microstructure and hardness of CrTiAlCN coatings by Awais Akhtar, Anand Vyas, Haihui Ruan

    Published 2025-05-01
    “…The structural, morphological, surface chemical binding states, nanostructure, and nanohardness of the CrTiAlCN coatings were analyzed using microstructural and mechanical characterizations. The results reveal that increasing carbon content considerably influences the microstructural evolution of the CrTiAlCN coatings, driving a transition from columnar morphology to a more compact and refined structure. …”
