Abstract

The invention provides a laser cladding method for recovering and reusing processing debris. In order to overcome the problem of high price of laser cladding powder. The laser cladding method selectsto recover a turning processing debris, uses high-energy ball milling mechanical agitation to remove an oxide film on the surface of a powder material, continues high-energy ball milling and agitationafter cleaning, until the debris is crushed into powder, so as to replace the laser cladding material to realize the secondary reuse of waste material. Finally, the powder is preset with the surfaceof the base material, and the coating is prepared by the laser cladding equipment. The laser cladding method adapts the method of reusing the turning processing debris, so that the manufacturing costof laser cladding powder is saved and the utilization rate of resources is improved; and is a green manufacturing mode with significant benefits.

Description

technical field [0001] The invention belongs to the field of surface engineering, and relates to a laser cladding method for recycled processing debris. Background technique [0002] Laser cladding technology is an emerging surface modification and processing technology. It uses laser beams as heat sources to melt alloy powders and forms a metallurgical bonded surface coating on the surface of the base alloy. Its research history originated in the 1970s. In the 1980s, laser cladding technology has developed into a frontier topic in the fields of surface engineering, tribology, and applied lasers. After the 1990s, related scientific research and application development have been rapidly developed. develop. As an effective means of material surface modification technology, laser cladding technology can significantly improve the strength, hardness, wear resistance, high temperature oxidation resistance, corrosion resistance and other properties of the surface of metal material...
