Abstract

The invention relates to a method and device for preparing a diamond-like carbon coating by cladding a carbon nanotube with fiber laser. The carbon nanotube is cladded with a fiber laser; the carbon nanotube is molten quickly by absorbing laser energy to form liquid carbon, and is cooled at an extremely high cooling speed; a diamond core grows, and undergoes phase change within an extremely short period of time; a part of carbon nanotube phases turn into diamond phases; the slightly-molten surface layer of a substrate material undergoes molecular level and atomic level diffusion, so that a strong metallurgically-bonded diamond-like carbon coating is formed; unbalanced condensation is led by an extremely high cooling speed; and an obtain diamond structure is fine and is approximate to a nanostructure. A used fiber laser head is coaxially connected with a powder spray head; processing is performed in a vacuum cavity; a laser beam is fully superposed with a carbon nanotube beam; and preparation of diamond-like carbon coatings of any shape and three-dimensional processing can be performed in cooperation with a flexible processing system of a six-degree-of-freedom robot.

Description

technical field [0001] The invention belongs to the technical field of surface engineering, and particularly relates to a method and a device for preparing a diamond-like thin film coating by cladding carbon nanotubes with a fiber laser. Background technique [0002] The diamond-like carbon film is an amorphous carbon film. When there are more diamonds in it than the graphite phase, the film exhibits characteristics similar to diamond, with ultra-high hardness, conductivity and other properties, and at the same time has a unique tribology. It can be widely used in mechanical, electronic, optical, thermal, acoustic, medical and other fields, and has good application prospects. The methods for preparing diamond-like carbon films mainly include physical vapor deposition (PVD), chemical vapor deposition (CVD), specifically ion beam assisted deposition, magnetron sputtering, vacuum cathode arc deposition, pulsed laser deposition and plasma enhanced deposition. chemical vapor dep...
