Abstract

Para disminuir el desgaste en los sistemas tribológicos frecuentemente se acostumbra a endurecer localmente aquellas
zonas sometidas a desgaste. En el presente trabajo, para incrementar la dureza y la resistencia al desgaste del acero AISI
W112 se empleó un láser de Nd:YAG. Las características de fricción y desgaste del acero AISI W112 en condiciones de
contacto deslizante en fricción seca con el acero 65MN4 fueron evaluadas para tratamientos convencionales luego de su
irradiación con láser. En el trabajo se presentan además las transformaciones que ocurren durante el tratamiento con láser,
así como la influencia de los parámetros operacionales del láser en la profundidad de la capa endurecida y las
características tribológicas. El trabajo experimental corroboró que la resistencia al desgaste del acero AISI W112 es varias
veces superior en comparación con los tratamientos convencionales.


Palabras claves: Comportamiento tribológico, endurecimiento lineal, tratamiento superficial con láser.

Abstract.
Diminishing wear in tribological systems is usually done by locally hardening those areas subject to wear. In this paper is
presented the increasing of hardness and resistance to wear of AISI W112 steel by means of a Nd:YAG laser. The
characteristics of friction and wear of AISI W112 steel under sliding contact in dry friction conditions with the 65MN4
steel were evaluated for conventional treatments and after laser irradiation. In the work are presented the transformations
that take place during the laser treatment, as well as the influence of the laser operational parameters in the depth of the
hardened layer and the tribological characteristics. The experimental work corroborated that the resistance to wear of AISI
W112 steel is several times superior in comparison with conventional treatments.


Key words: Tribological behavior , lineal hardening, laser superficial treatment.
