摘　　要：针对冷金属过渡(CMT)电弧增材制造技术存在的表面成形质量差、制件内部易形成孔隙等冶金缺陷、微观组织与性能调控困难等问题,从控形与控性两个方面出发,对CMT电弧增材制造技术研究进展进行了综述。首先,对CMT技术的原理及特点进行了分析与梳理;然后,对CMT电弧增材制造技术在“形”与“性”方面的调控方式进行了总结,具体阐述了制件的表面成形质量、内部冶金缺陷、微观组织与性能3个方面的调控方式;最后,通过对现有调控方式的局限性进行了分析,提出了CMT电弧增材制造技术的未来发展趋势。研究结果表明:未来CMT电弧增材制造技术的发展趋势包括:(1)“形”与“性”协同控制与优化;(2)CMT电弧增材制造难焊材料及复合材料;(3)调控方式的理论机制规律。In view of the fact that the cold metal transfer(CMT)wire arc additive manufacturing technology existed some problems,such as poor surface forming quality,easy formation of internal pores and other metallurgical defects in the parts,and difficulty in controlling microstructure and properties,the research status of the CMT wire arc additive manufacturing technology was reviewed from the aspects of the shape and property control.Firstly,the principle and characteristics of the CMT technology were analyzed and sorted out.Secondly,the control methods of the CMT wire arc additive manufacturing technology in the field of“shape”and“property”were summarized,and the control methods in three aspects of the surface forming quality,internal metallurgical defects,microstructure and properties of parts were expounded in detail.Finally,the future development trend of the CMT wire arc additive manufacturing technology was proposed by analyzing the limitations of the existing control methods.The results show that the development and research trend of the CMT wire arc additive manufacturing technology in the future includes the coordinated control and optimization of“shape”and“property”,the CMT wire arc additive manufacturing of the refractory materials and composite materials,and the theoretical mechanism and regulation rules of the control methods.
