Resumen
Additive manufacturing of metals has become increasingly popular in the industrial sectorover the last decade. Among the techniques available, the so-called ‘wire arc additivemanufacturing’ (WAAM) stands out for its ability to manufacture parts larger than one cubicmetre in a reasonable time. It also significantly reduces material waste, energy consumption, greenhouse gas emissions and the time from when the need for a particular componentarises until it is put into service. However, although this technique originated more than acentury ago, its research, development and application in the industrial environment arerelatively recent, so studies related to the corrosion behaviour of components manufacturedby WAAM are still scarce.In this paper, the pitting corrosion resistance of additively manufactured austenitic stainlesssteel samples is studied by potentiodynamic test in sodium chloride solution (35 g/L).Results are compared with other austenitic stainless steels obtained for industriallymanufactured.
