Friction-Lead Confined Interface Catalysis for 2D Material Growth for Superlubricity of a-C:H films

Superlubricity specifically refers to the phenomenon where friction vanishes, and experimentally, the state where the coefficient of friction approaches zero is termed superlubricity. This revolutionary technology implies near-zero friction and near-zero wear. Addressing the challenge of achieving superlubricity over sub-millimeter scales with two-dimensional materials, the authors propose a novel approach of in situ growth of two-dimensional materials at the friction interface to achieve superlubricity. Based on this, they introduce for the first time the concept of friction-induced interface-confined catalytic generation of two-dimensional materials to realize superlubricity. This book briefly introduces noble metals/hydrogenated amorphous carbon, molybdenum disulfide/hydrogenated amorphous carbon, ammonium thiomolybdate/hydrogenated amorphous carbon, and other multilayer structures based on this concept, achieving in situ growth of two-dimensional materials at the friction interface and superlubricity on steel surfaces from various perspectives.
