| description | Performance against abrasive wear was evaluated (in compliance with the ASTM G-65 standard) for both wear plates and hard coatings applied by electric welding. The characterization of the coatings was achieved by using hardness tests, optical microscopy and scanning electron microscopy (SEM). Although it was observed a direct correlation between hardness and wear resistance, a linear growth pattern was not followed. Besides the information from the hardness tests, data regarding the distribution and shape of the carbides in the welding bead are also necessary to choose the hard coating applied by welding, to protect against abrasive wear. Base metal and coatings had satisfactory joint, due to their dilution; the first welding layer had less hardness than the third welding layer. |

Abrasión Desgaste Láminas Revestimiento Soldadura SMAW Tribología Performance against abrasive wear was evaluated (in compliance with the ASTM G-65 standard) for both wear plates and hard coatings applied by electric welding. The characterization of the coatings was achieved by using hardness tests, optical microscopy and scanning electron microscopy (SEM). Although it was observed a direct correlation between hardness and wear resistance, a linear growth pattern was not followed.

Se evaluó el desempeño frente al desgaste abrasivo de láminas antidesgaste y recubrimientos duros aplicados por soldadura eléctrica, utilizando la norma ASTM G-65. Para caracterizar los recubrimientos, a algunos depósitos se les hicieron pruebas de dureza, microscopia óptica y microscopia electrónica de barrido (SEM). Se observó que a medida que aumenta la dureza, aumenta la resistencia al desgaste, pero también se evidenció que no se sigue un patrón de crecimiento lineal. Por lo tanto, la dureza es información que nos puede dar un criterio de selección, pero no puede ser el único factor a la hora de elegir un recubrimiento duro aplicado por soldadura para la protección contra el desgaste abrasivo, ya que hay otros factores que afectan el desgaste, como la distribución y forma de los carburos en el cordón de soldadura. La unión de los recubrimientos con el metal base es muy buena. La dilución con el metal base hace que la dureza del primer pase de soldadura sea menor que la del tercer pase.
