Method for preparing component through laser additional material and system for preparing laser additional material

Abstract

The invention discloses a method for preparing a component from a laser additional material and a system for preparing the laser additional material, and relates to the technical field of preparing ofthe additional material. The problems that when the additional material is prepared through coaxial feeding and laser precipitating of premixed powder, due to the different ratio and the long-term and long-distance conveying, the airborne conveying segregation phenomenon and heavy-light separation phenomenon occur before the powder reaches a molten bath, and compositions in the composite component formed through laser precipitating are not evenly distributed are solved. A device for preparing the additional material through lasers is applied to the method. The method includes the steps that apowder feeder controls different types of material powder output by at least two powder feeding tanks to converge at a same position of a base material face according to the additional material preparing strategy of the component so that the different types of material powder output by at least two powder feeding tanks can flow on the base material face to form a mixture; and a laser device controls a laser machining head to perform melting and sintering on the mixture according to the additional material preparing strategy of the component to obtain the component. The method for preparing the component from the laser additional material and the system for preparing the laser additional material are used for preparing the additional material.

Description

Technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a method for laser additive manufacturing of components and a laser additive manufacturing system. Background technique [0002] Laser additive manufacturing technology is an automated forming technology developed by integrating the latest technologies such as computers, numerical control, lasers and new materials. It can discretize the complex three-dimensional structure into a series of layers for processing, which greatly reduces the processing difficulty. [0003] At present, the coaxial powder feeding laser deposition technology can be used to process the various components required by the composite material into composite material components. However, the existing coaxial powder feeding laser deposition technology additively manufactures composite material components. The uneven distribution of internal components causes serious impact on the performance of composi...
