采用热扩渗技术,在低碳钢表面制备Fe-Ni合金层,研究制备温度对合金层组织结构和耐腐蚀性能的影响。结果表明,合金层表面的化学成分存在区域差异,这一差异随着处理温度的升高而减小。合金层表面的耐腐蚀性能随着处理温度的提高和Ni含量的增加而逐渐增强。 The thermal expansion technique was used to prepare the Fe-Ni alloy layer on the surface of low-carbon steel to study the effect of preparation temperature on the microstructure and corrosion resistance of the alloy layer. The results show that the chemical composition of the alloy layer on the surface of the region there is a difference, the difference decreases with increasing processing temperature. The corrosion resistance of the alloy layer surface gradually increases with the increase of the treatment temperature and Ni content.
