Resumen:
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 martensite in the coating, and increasing the
dimensions of the eutectic zone. Also, V originated the formation of VC,
in addition to the Cr7C3 carbides present for the two alloy systems.
These microstructural modifications provoked that coatings deposited
using the Fe-Cr-Mn-V-C alloy system show a significantly higher abrasive
wear resistance.
