Precise graphenization of ultra-thin diamond coatings achieved without substrate damage
Here, researchers from Nanjing University of Aeronautics and Astronautics propose to control thermal stress at coating interfaces during laser induction processes and demonstrate a novel process for precisely graphenizing ultra-thin diamond coating surface through laser induction and mechanical cleavage, without damaging the substrates. Their work provides an effective and cost-efficient avenue to overcome application bottlenecks in engineered diamond surfaces, expanding their use in friction pairs such as cutting tools, bearings, and mechanical seals. Moreover, it may facilitate advancements in multicarbon heterostructures and their preparation methods, supporting potential applications in electronics, aviation, and biomedicine involving diamond, graphene, and all-carbon devices.
