Abstract
This study investigates an approach to enhancing the tribological properties of CVD diamond films by modifying their structure. The approach is based on periodic renucleation of the film during the synthesis process. A comparative analysis was conducted with films of a microcrystalline structure and a standard multilayer structure, consisting of alternating microcrystalline and nanocrystalline diamond layers. The results demonstrate that the periodically renucleated diamond film retains all the features of the multilayer structure, including low surface roughness of 311 nm, tensile residual stress of 2.8 GPa, low coefficient of friction of 0.08, and low wear rate of counter body of 2.19 × 10−6 mm3N−1m−1. Moreover, the periodically renucleated diamond film exhibits significantly improved wear resistance, with a 43 % lower wear rate compared to standard multilayer film.
