Abstract

The invention discloses a processing method and device for a nano-scale morphology of a metal material surface, and aims to solve the problem that an existing method and an existing device do not have a soft tool for processing the nano-scale morphology of a hard workpiece surface. The processing method comprises the following steps of: selecting tools made of different materials for to-be-processed metal workpiece surfaces; regulating vibrating frequency and amplitude of vibration of an ultrasonic vibrating device according to molecule or atom quantity preset ranges of the tools in preset nano-scale morphologies obtained on the metal workpieces; driving a clamp to clamp the to-be-processed metal workpieces by a clamping air cylinder; positioning initial processing positions of the metal workpieces to positions below the tools by a XY drive table; starting the ultrasonic vibrating device for enabling the tools to generate micro vibration before processing; enabling a workpiece moving platform and a micro feeding device to move in a matched mode, enabling the micro feeding device to feed according to preset feeding amount, and processing out preset nano-scale morphologies of the metal workpieces. According to the processing method disclosed by the invention, the soft tool is utilized for transferring and diffusing a metal workpiece surface into a mass-transfer film, so that energy gradient of the workpiece surface is improved, and damages on the workpiece are avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and manufacturing of surface topography of materials, and in particular relates to a method and device for processing nanoscale topography on the surface of metal materials. Background technique [0002] The morphology of surface micro-nano structures has important applications in machining. The micro-nano morphology has excellent anti-friction performance, such as the micro-pore (groove) structure of some surface structures helps the formation of a dynamic lubricating oil film, thereby increasing lubrication and reducing friction. At the same time, the micro-nano morphology has some super-hydrophobic or super-hydrophilic properties, and has important applications in metal self-cleaning, anti-corrosion and wear resistance. At present, there are roughly physical and chemical methods for the surface topography of micro-nano structures. The physical methods include simple mechanical p...
