摘要：

In this work, it has been possible to deposit a Ni-P alloy by electroless nickel plating on the surface of a low carbon steel sample, produced by additive manufacturing. The samples were characterized by SEM, EDS, XRD, white light interferometry, Vickers microhardness, EIS, and ENM techniques. A coating of an amorphous nature is obtained at a deposition rate of 9.19 mu m/h, with high homogeneity, average roughness of 86.52 nm, good adhesion to the substrate, and a hardness of the order of 500 HV. The electrochemical characterization allows evidence of a significant increase in corrosion resistance for the coated material with a noise resistance of 20 k Omega-cm(2) after 576 h of evaluation.
