Abstract

To produce new materials with an additive manufacturing method the use of composition correction powder-cored wire is an attractive approach. In this article the powder-cored wire with high content of Fe, Cr, Ni, Mn, Mo alloying elements and Ti as stabilizing agent was used. The energy-dispersion analysis was used to determine the composition of the wire. Corrosion tests were carried out in FeCl3 solution to determine the resistance of the material against pitting corrosion. We also studied the influence of heat treatment on the corrosion resistance of the printed material. During the growth of the sample the powder-cored wire components are diluted within the deposited layer/substrate boundary and then redistributed during the high-temperature annealing thus having a negative effect on the corrosion resistance of the final product.To produce new materials with an additive manufacturing method the use of composition correction powder-cored wire is an attractive approach. In this article the powder-cored wire with high content of Fe, Cr, Ni, Mn, Mo alloying elements and Ti as stabilizing agent was used. The energy-dispersion analysis was used to determine the composition of the wire. Corrosion tests were carried out in FeCl3 solution to determine the resistance of the material against pitting corrosion. We also studied the influence of heat treatment on the corrosion resistance of the printed material. During the growth of the sample the powder-cored wire components are diluted within the deposited layer/substrate boundary and then redistributed during the high-temperature annealing thus having a negative effect on the corrosion resistance of the final product.

粉末包芯线材和铁素体钢基体电子束增材制造Fe-Cr-Ni-Mn-Mo-Ti钢的耐腐蚀性能

采用成分校正粉芯线的增材制造方法生产新材料是一种很有吸引力的方法。本文采用高含量Fe、Cr、Ni、Mn、Mo合金元素和Ti作为稳定剂的粉末包芯线材。利用能量色散分析确定了金属丝的成分。在FeCl3溶液中进行腐蚀试验，以确定材料抗点蚀的能力。我们还研究了热处理对印刷材料耐腐蚀性能的影响。在样品生长过程中，粉芯线材成分在沉积层/衬底边界内被稀释，然后在高温退火过程中重新分布，从而对最终产品的耐腐蚀性产生负面影响。采用成分校正粉芯线的增材制造方法生产新材料是一种很有吸引力的方法。本文采用高含量Fe、Cr、Ni、Mn、Mo合金元素和Ti作为稳定剂的粉末包芯线材。利用能量色散分析确定了金属丝的成分。在FeCl3溶液中进行腐蚀试验，以确定材料抗点蚀的能力。我们还研究了热处理对印刷材料耐腐蚀性能的影响。在样品生长过程中，粉芯线材成分在沉积层/衬底边界内被稀释，然后在高温退火过程中重新分布，从而对最终产品的耐腐蚀性产生负面影响。
