Abstract
A method for shape-performance control by ultrasonic rolling combined with selective laser melting is provided, which includes following steps: S1, establishing a three-dimensional model of a component to be processed, and setting printing process parameters; S2, after nitrogen gas is filled into a forming cavity to reduce an oxygen content to a preset value, lowering a forming substrate and raising a powder substrate, laying powder from the powder substrate onto the forming substrate by a scraper, recovering excess powder, and after the laying is completed, melting the powder by a laser galvanometer to form a solid layer, and cycling for several times; S3, performing ultrasonic rolling on a surface of the solid layer; S4, cycling steps S2 and S3 until the component is formed, and ending the cycling; and S5, performing ultrasonic rolling on a surface of a formed component to obtain a solid component.
