摘要

针对镁合金耐蚀性和耐磨性较差，以及传统熔焊方法难以有效连接镁和钢等问题，提出了采用搅拌摩擦钎焊技术连接AZ31B镁合金和316L不锈钢。首先，利用搅拌摩擦钎焊工艺制备不同厚度Zn箔和Ni箔的镁/钢搭接接头；然后，从接头的润湿性、微观组织和力学性能等方面研究其可行性；最后，阐明了不同钎料的界面反应特征和机制。实验结果表明：Zn箔只对镁合金一侧有良好的润湿性，对不锈钢表面几乎不润湿，Zn箔熔化后在接头处形成α-Mg+MgZn的共析组织，接头最大剪切强度为27.38 MPa，表现为脆性断裂；Ni箔对两侧母材润湿良好，在接头处形成亚共晶组织α-Mg

Abstract

To address the poor corrosion and wear resistance of magnesium alloys

as well as the challenges of effectively joining magnesium and steel using traditional welding methods

the use of stir friction brazing technology is proposed to connect AZ31B magnesium alloy and 316L stainless steel. First

different thicknesses of Zn and Ni foils are used to fabricate magnesium/steel lap joints using the stir friction brazing process. The feasibility of these joints is then examined from the perspectives of wettability

microstructure

and mechanical properties. Finally

the interfacial reaction characteristics and mechanisms of different brazing materials are elucidated. Experimental results indicate that Zn foil exhibits good wettability on the magnesium alloy side but almost none on the stainless-steel surface. When the Zn foil melts

it f

orms a eutectoid structure α-Mg+MgZn at the joint

with a maximum shear strength of 27.38 MPa

resulting in brittle fracture. Conversely

Ni foil demonstrates good wettability on both base materials

leading to the formation of a hypoeutectic structure α-Mg

and eutectic structure α-Mg+Mg

reaching 58.24 MPa at a thickness of 0.03 mm

exhibiting a combination of brittle and ductile fracture. The proposed stir friction brazing process can achieve high density

good wettability

wide single-pass welds

and high strength in magnesium alloy/stainless steel lap joints through interlayer optimization.
