| 摘 要： | 为了提高Q235钢表面的耐蚀性和硬度等性能,采用TIG堆焊技术对Q235钢进行表面堆焊不锈钢试验,在30个试样中选取堆焊效果较好的4个试样,分析了其组织的宏观和微观形貌,选择15#试样堆焊层进行了腐蚀试验,并与Q235钢板的硬度进行了比较分析。试验结果表明,通过在Q235钢板表面堆焊不锈钢进行表面处理,其表面硬度有明显的提高,堆焊后Q235钢板表面堆焊层的耐蚀性比Q235钢母材的耐蚀性强。

| Abstract: | In order to improve the surface performance of Q235 steel, such as corrosion resistance, hardness and so on, in this article, it adopted TIG technology to conduct surface overlaying welding on stainless steel, carried out 30 groups of tests,selected four samples which possessing good overlaying welding effect, analyzed the macroscopic and microscopic morphology, and selected 15# specimen to conduct corrosion test. Finally, it is concluded that surface overlaying welding on stainless steel for Q235 steel, the surface hardness of steel plate obviously be increased, the corrosion resistance of Q235 steel after surfacing welding is better than that of Q235 steel base metal. |
