Mejora de la resistencia al desgaste abrasivo de un revestimiento Fe-Cr-Mn-C mediante la adición de V

ABSTRACT The aim of this work is to increase the abrasive wear resistance of a coating, applied on plates of AISI 1020 carbon steel, using tubular coated electrodes with the Fe-Cr-Mn-C alloy system. In order to achieve this increase, V was added to the alloy system. The resulting coating were studied using optical microscopy (MO), X-ray diffraction and microhardness tests. Wear tests were carried out in accordance with the procedure of ASTM G 65-B. Results showed that the addition of V to the Fe-Cr-Mn-C system caused significant microstructural modifications, decreasing the amount of martensit...
