摘　　要：采用实验室化学浸泡、电化学腐蚀试验及维氏硬度测量技术研究了DSS2205爆炸及热轧复合板复层性能,利用金相显微镜、透射电镜分析了复层组织,并与复合前的DSS2205进行了对比分析。结果表明:相比复合前的DSS2205不锈钢,轧制和爆炸复合板复层腐蚀性能略有下降,硬度增加,但轧制复合板复层腐蚀性能优于爆炸复合板复层;轧制复合板复层组织为棒状奥氏体不完全呈一条直线分布于铁素体上,奥氏体发生再结晶;爆炸复合板复层仍为复合前的奥氏体和铁素体间隔分布带状组织,铁素体和奥氏体均出现变形。The properties of composite layer of DSS2205 rolled and exploded clad plates were studied by means of chemical immersion in laboratory,electrochemical corrosion test and Vickers hardness measurement. The microstructure was analyzed by metallographic microscope and transmission electron microscope,which was compared with DSS2205 stainless steel before cladding. The results showed that the corrosion properties of composite layer of rolled and exploded clad plate were slightly decreased and the hardness was increased compared with DSS2205 stainless steel before cladding. But the corrosion properties of composite layer of the rolled clad plates were better than those of explosion clad plates. The microstructure of the composite layer of rolled clad plates was composed of rodlike austenite,which was not distributed in a straight line on the ferrite,and the austenite had recrystallization. Meanwhile,the microstructure of composite layer of the explosion clad plates was still composed of band structure with interval distribution of austenite and ferrite before cladding. The both ferrite and austenite were deformed.
