ANALYSIS OF WEAR AND TEAR OF WORKING ELEMENTS WITH A REPLACEABLE CUTTING EDGE IN AN ABRASIVE SOIL MASS
Journal Title: Tribologia - Year 2017, Vol 273, Issue 3
Abstract
This paper presents an analysis of the wear and tear process of different technological solutions of plough blades with a replaceable cutting edge. The experiment was conducted under natural operating conditions. Workpieces made of B27, Hardox 500, and Hardox 500 with padding weld, and two types of boron steel with non-hardfaced and hardfaced cutting edges were tested. The analyses of chemical composition and microstructure were performed using light microscopy and scanning electron microscopy methods. Operational research included the measurement of mass changes and geometry in the characteristic points of the plough blades. Based on the results obtained, it was found that the components made of Hardox 500 steel with padding welding were more durable than component without the padding layer. In contrast, the weight loss intensity was similar for all the examined materials.
