铝合金表面特性对其胶接性能影响的研究进展

摘要

不同的表面处理方法会导致铝合金表面的表面理化特性发生改变,从而对铝合金板材与胶黏剂的界面结合强度以及胶接接头的耐腐蚀性能有很大的影响.本文从铝合金表面粗糙度、微观织构、表面氧化层和涂层化学特性等方面入手,对铝合金胶接接头的界面强度和耐腐蚀性能影响的研究现状进行了综述.探讨了铝合金胶接研究发展趋势,并认为铝合金表面理化特性的参数化表征以及表面特性与胶接性能的关系模型建立等方面是今后研究的重要方向.%Surface physicochemical properties of aluminum alloy can be changed by different surface treatment methods,which determines the performance of adhesively bonded joints.This paper reviews the research status on the interfacial bonding strength and corrosion resistance of adhesively bonded aluminum alloys joints from the perspectives of surface roughness,surface micro-structure,surface oxide and coated chemistry properties.Then the problems and development of adhesively bonded aluminum alloys are discussed.The characterization of the aluminum surface physical and chemical properties and the relation model between the surface properties and the adhesive performance are considered to be focused directions for the further research.
