摘要
针对不锈钢-碳钢层合板制备方法中结合面存在的缺陷问题,采用激光熔覆法制备金属层合板。调整激光功率和扫描速度两个主要工艺参数,研究其对层合板金相组织的影响。通过不锈钢-碳钢层合板金相组织分析以及拉伸试验研究,优化层合板激光熔覆工艺参数。结果表明:随着激光能量密度的增大,不锈钢-碳钢层合板界面波高依次呈0.01~0.03 mm、0.08~0.10 mm和0.11~0.14 mm三种形态,且熔覆层厚度逐渐增加。随着界面波高的增大,屈服强度逐渐增大,当不锈钢-碳钢层合板界面金相组织形态呈波高为0.11~0.14 mm时,屈服强度为410 MPa。激光熔覆制备方法获得了不锈钢-碳钢冶金结合及组织性能均良好的层合板,屈服强度和延伸率均达到了不锈钢层合板的标准要求,表明此工艺方法是可行的,为激光熔覆制备层合板的广泛应用提供了理论和试验依据。
Abstract
Due to quality defects on the surface of stainless and carbon steel laminated plates prepared conventionally, laser cladding is introduced for preparing metal laminated plates. By adjusting two main process parameters of the laser power and scanning speed, their influences on the metallographic structure of laminated platesby laser cladding are investigated. Then the parameters are optimized according to metallographic structure analysis and tensile test of stainless-carbon steel laminated plates. The results show that: with the decrease of the energy density of the laser, stainless steel laminated plates interface is arranged in three microstructure morphology, which have wave heights of 0.01~0.03 mm, 0.08~0.10 mm and 0.11~0.14 mm, and the layer thickness increases gradually. Meanwhile, the yield strength increases as the interface wave height increases. When the wave height of the interface of stainless steel laminated plates is 0.11~0.14 mm, thehigh yield strength of 410 MPa is obtained. Stainless-carbon steel laminated plates prepared by laser cladding have strong metallurgy bonding quality and good microstructure properties. The tensile strength and elongation indicators have met the requirements of the standard of stainless-carbon steel laminated plates. This method is feasible, and provides theoretical and experimental basis for the wide application of laser cladding preparation of laminated plates.
