摘要: Abstract We report a comprehensive study on the protective, functional and microstructural properties of filtered cathodic vacuum arc (FCVA) deposited ultrathin carbon overcoats (COCs), which are being considered as potential candidates for future media recording technology such heat-assisted magnetic (HAMR). Specifically, influence C + ion energy (50–345 eV) film thickness (0.5–3.2 nm) these were investigated supported with Raman X-ray photoelectron spectroscopy (XPS). Finally, an optimized deposition recipe has been proposed to develop (≤2.0 nm) yet continuous COC improved wear corrosion resistance compared thicker conventional COCs (~2.7 nm).
