EFFECT OF THE ANGLE OF IMPACT OF AN ABRASIVE SOIL MASS ON STEEL WEAR INTENSITY
Journal Title: Tribologia - Year 2018, Vol 279, Issue 3
Abstract
This article presents a study into the effect of the rake angle of the working surface of a specimen made of Hardox Extreme steel on abrasive wear intensity. The study was conducted using the “rotating bowl” method in two types of an abrasive soil mass at three specimen rake angles of 0˚, 12˚, and 17˚. No significant differences in the wear intensity were observed for a heavy abrasive soil mass, while for a light abrasive soil mass, an increase in the wear intensity was observed with an increase in the rake angle, with the greatest increase in the wear intensity occurring after a change in the rake angle from 0˚ to 12˚. Increasing the rake angle from 12˚ to 17˚ resulted in no significant change in the wear intensity. In the light abrasive soil mass, non-zero specimen rake angles increased the dynamic impact of loose abrasive wheels. The appearance of the surface of specimens subjected to abrasion under these conditions indicated a high proportion of erosive wear accompanying the scratching and ridging wear.<br/><br/>
