EFFECT OF LASER HARDENING OF STEEL ON THE WEAR PROCESS IN AN ABRASIVE SOIL MASS

Journal Title: Tribologia - Year 2018, Vol 280, Issue 4

Abstract

This paper presents the results of tests for the effects of laser hardening on the course and intensity of wear of 38GSA (38MnSi4) and Hardox 600 steels in an abrasive soil mass. The tests were carried out under laboratory conditions, using a “rotating bowl” type machine. Two types of soil, i.e. light and medium, were used as the abrasive mass. Based on the obtained test results, it was found that hardness decreased (in relation to asdelivered condition). The performed laser surface hardening process significantly increased the abrasive wear resistance only for 38GSA (38MnSi4) steel. As regards to Hardox steel, the hardening treatment reduced the abrasive wear resistance index compared to the as-delivered condition of the steel.<br/><br/>
