摘要：

In this work, a detailed comparison of corrosion behavior and microstructural features of the Cr-rich stainless steel coatings manufactured by conventional laser metal deposition (CLMD) and extreme high-speed laser metal deposition (EHLMD) was firstly investigated. Results indicate that the EHLMD coating exhibited a superior corrosion resistance with a significantly higher the polarization resistance (Rp = 709.79 kΩ. cm2) compared to the CLMD coating (Rp = 356.69 kΩ. cm2) in 0.598 mol/L NaCl solution at room temperature. This was ascribed to the differences in microstructure characteristics of the coatings prepared by the two additive manufacturing processes. © 2021 Elsevier Ltd
