研究了不锈钢———碳钢单面、双面复合板爆炸焊接质量 ,结合界面的微观结构 ,剪切强度及耐蚀性能 .结果表明 ,单、双面不锈钢———低碳钢爆炸焊接复合板的结合界面均为波状结构 ,结合面两侧存在一定组织变形 ,近界面处为角结晶组织 ,稍远处为拉伸变形后的纤维状组织 .结合界面碳钢一侧过渡区存在增碳区 ,不锈钢一侧有一个脱碳层 .双面复合界面的结合过渡区约为单面的 1.5倍宽 ,脱碳区也接近单面的 1.5倍 .采用切割爆炸焊接法有利于改善不锈钢———低碳钢复合板的边缘焊合 .在同一基板上进行双面不锈钢复合时 ,第一面复合界面的剪切强度比第二面复合界面的差 .无论是单面 ,还是双面复合板 ,其界面结面强度均由起爆端向末端逐渐降低 .结合界面的脱碳层对复合板的耐蚀性能无明显影响
The quality of explosion welding of stainless steel-carbon single-sided and double-sided composite plates was studied, and the microstructure, shear strength and corrosion resistance of the interface were studied.The results show that the single and double-sided stainless steel --- low carbon steel explosive welding composite The bonding interfaces of the plates are all wavy structures with some deformations on both sides of the bond plane, with angular crystalline structures near the interface and fibrous structures distorted slightly from the interface. Area, a decarburized layer on the side of the stainless steel.The combined transition area of the double-sided composite interface is about 1.5 times as wide as the single side, and the decarburization area is also close to 1.5 times of that of the single side, the cutting explosion welding method is beneficial to improve the stainless steel- - Edge welding of mild steel clad plate When double-sided stainless steel is clad on the same substrate, the shear strength of the first-side composite interface is worse than that of the second-side composite interface.Whether single-sided or double-sided composite board , The interface strength of the interface decreased gradually from the detonation end to the end.The decarburized layer with the interface had no significant effect on the corrosion resistance of the composite board
