钛及钛合金具有良好的耐腐蚀性,被广泛应用于各种化学反应容器制造、热交换器材料等防腐蚀领域,但其应用范围因成本过高而受到限制.钛钢复合板同时兼具钛的耐蚀性和钢的强韧性,又具有良好的性价比,拥有广泛的工程应用前景,成为近年来的研究热点.对国内外近十几年来关于钛钢复合板的研究情况进行综合评述,概括了钛钢复合板的典型制备方法,重点讨论了界面组织特征和界面结合机理,以及热处理温度对界面特征和结舍强度的影响规律.最后结合相关文献的分析以及实际工程的需求,指出了钛钢复合板未来的研究方向和发展前景.
Titanium and its alloys have been widely used in anti-corrosion fields such as chemical reaction vessels production,heat exchanger owning to their good corrosion resistance.However,the application of titanium and its alloys have been hindered by their relatively high cost.Recently,titanium-steel clad plate has attracted much attention in research,because of the good corrosion resistance of titanium,the strength and toughness of steel,as well as the good cost performance.This paper aims to review the research status of the titanium-steel clad plate in decades,among which the typical preparation methods of the titanium-steel clad plate are summarized.Meanwhile,the characteristics of interfacial microstructures,the interfacial bonding mechanism,together with the effects of heat treatment temperature on the interfacial characteristics and bonding strength are emphatically discussed.At last,based on the relevant literature analysis and requirements in the actual industry,the research and development trends of the titanium-steel clad plate are proposed.
