Resumen
Debido a su buena combinación de propiedades y a su aplicación en el sector automotriz y ferroviario, entre otros, los aceros bainíticos han sido objeto de estudio al modificar su composición química mediante el uso de diferentes aleantes con el fin de mejorar su resistencia, como es el caso del boro, el cual es un elemento que permite incrementar las propiedades mecánicas del acero y su comportamiento frente a fenómenos como el desgaste al ser utilizado en pequeñas cantidades. En el presente trabajo, por medio de ensayos de cámara salina y de polarización potenciodinámica, se estudió la influencia del boro en aceros con microestructura bainítica frente a fenómenos como la corrosión al variar su porcentaje en cada muestra analizada, lo cual se desarrolló a partir de la medición de parámetros como el porcentaje de área corroída y la densidad de corriente. Aunque en los resultados de cámara salina no se observó una influencia significativa del boro, en los de polarización potenciodinámica se apreció una mayor reducción en la densidad de corriente para el acero que contenía mayor porcentaje de boro en su composición, lo cual indica una mayor resistencia a la corrosión frente a los aceros que tenían un menor porcentaje de este elemento.
