Metallization of polymeric materials is a process that manages to combine the properties of polymers and metals, to expand its range of applications. In this research, the deposition of a Zn-Al alloy on a polymeric substrate (ABS) using wire flame spray was carried out, with a predominant advantage by not using chemical surface preparation processes, thus obtaining materials at low cost, friendly to the environment, without affecting the properties of the substrate, avoiding its degradation by temperature, and gaining a level of electrical conductivity appropriate to nature of the coatings. Substrate roughness is measured by interferometry, coating morphology by SEM, the composition by EDS, structure by XRD, adhesion by Pull-Off, and electrical resistivity is evaluated using the 4-point test. The SEM results show a coating with a thickness of the order of 89 µm, homogeneous in its composition with a Zn and Al crystalline structure, an adhesion strength of 888 N, with a porosity of 0.87% with an average pore size of 10 µm. The electrical conductivity study of the coated material shows a good electrical response, with a value of 2682 S/m.
