Research Progress of Friction Stir Additive Manufacturing

摘要:

介绍了基于搅拌摩擦焊原理开发的固相增材制造技术，根据制备工艺差异，搅拌摩擦增材制造技术可分为3类，分别为基于薄板逐层堆积的搅拌摩擦增材制造技术、消耗金属粉材的固相搅拌摩擦增材制造技术及消耗金属棒材的摩擦表面增材制造技术。对上述3类搅拌摩擦增材技术的国内外研究现状进行了介绍和分析，并对基于搅拌摩擦的固相增材制造技术未来的发展进行了展望。

Abstract:

This study introduces solid-phase additive manufacturing technology based on the principle of friction stir welding. According to the difference in preparation processes， the friction stir additive manufacturing （FSAM） can be classified into three types， including friction stir additive manufacturing technology based on the layer-by-layer accumulation of plates， solid-phase friction stir additive manufacturing technology by consuming the metal powder， and friction surface additive manufacturing technology by consuming the metallic rod. Based on these three types of FSAM， this paper introduces and analyzes the current status of domestic and foreign research. Meanwhile， the possible challenges and corresponding prospects of stir-friction-based solid-phase additive manufacturing technologies in the future are summarized.
