    摘要:

    由于激光選區(qū)熔化(SLM)技術(shù)加工周期較短、易于成形結(jié)構(gòu)復(fù)雜的零件,現(xiàn)已廣泛應(yīng)用于生物醫(yī)療、航空航天、汽車和軍工制造業(yè)等領(lǐng)域。但是由于在成型過程中激光與粉末間復(fù)雜地相互作用,激光選區(qū)熔化制件的缺陷呈現(xiàn)出多樣化的特點,且控制難度加大,這在一定程度上限制了該技術(shù)的發(fā)展和應(yīng)用。對于飛濺缺陷的形成機(jī)制和控制方法的研究,是近年來研究的熱點之一?？偨Y(jié)了近年來的相關(guān)研究成果,將粉末、熔池及成形層作為線索,從飛濺物對成形件的影響、飛濺物形成原因、監(jiān)測和控制方法以及未來研究方向四部分闡述SLM過程中飛濺形成機(jī)制和控制方法,并展望了未來的發(fā)展方向。

    Abstract:

    Laser selective melting (SLM) technology has been widely used in biomedical, aerospace, automotive and military manufacturing industries because of its short processing cycle and easy to form parts with complex structure.SHowever, due to the complex interaction between laser and powder in the forming process, the defects of laser selective melting parts show diversified characteristics, and it is more difficult to control, which limits the development and application of this technology to a certain extent.SThe research on the formation mechanism and control methods of spatter defects is one of the research hotspots in recent years.SThis paper summarizes the relevant research achievements recently, taking powder, molten pool and forming layer as clues, expounds the spatter formation mechanism and control methods in the SLM process from four parts: the influence of spatter on formed parts, the cause of splash formation, the monitoring and control methods and the future research direction, and looks forward to the future development direction.
