Additive manufacturing as a major component of the “fourth Industrial Revolution” is getting more and more attention. Friction additive manufacturing technology (FAM) is a subdivision of additive manufacturing technology. Because of its solid-state characteristics, deposition by FAM shows better mechanical performance than other technologies such as powder bed fusion technologies. This paper presents a state-of-the-art survey on the development of FAM in three categories: (i) Friction stir additive manufacturing; (ii) Friction surfacing additive manufacturing; (iii) Metal powder assisted additive manufacturing. The underlying principles, process parameters, microstructure, mechanical properties, and existing problems are described and discussed in detail.

增材制造作为“第四次工业革命”的重要组成部分越来越受到关注。摩擦增材制造技术（FAM）是增材制造技术的一个细分领域。由于其固态特性，FAM 沉积显示出比粉末床熔融技术等其他技术更好的机械性能。本文介绍了三类 FAM 发展的最新调查：(i) 搅拌摩擦增材制造；(ii) 摩擦表面增材制造；(iii) 金属粉末辅助增材制造。详细描述和讨论了基本原理、工艺参数、微观结构、机械性能和存在的问题。
