THE STRUCTURAL PROPERTIES AND RESISTANCE TO ABRASIVE WEAR IN SOIL OF CREUSABRO STEEL
Journal Title: Tribologia - Year 2016, Vol 269, Issue 5
Abstract
The paper presents the results of abrasive wear resistance tests on Creusabro 4800 and Creusabro 8000 steel. The results obtained for laboratory samples were referred to the structure of the examined types of steel and to the basic indicators characterising their mechanical properties. As a result of the conducted tests, which used the methods of light and scanning microscopy, it has been concluded that, in its delivered condition Creusabro, steel exhibits a complex type of structure, characteristic for steel with the “TRIP effect.” The identified type of structure indicates a precisely adjusted chemical composition and the use of specialised heat treatment and forming processes in the production process of those materials. The abrasive wear resistance tests conducted by means of the “spinning bowl” method in real soil masses, i.e. light soil (loamy sand), medium soil (light till) and heavy soil (normal till), as well as the conducted measurements of hardness, have proven the strict dependence of the obtained indicators of abrasive wear resistance on the phase structure and on the status of the heat treatment of the tested steel. The results of abrasive wear resistance tests for Creusabro steel were referred to 38GSA steel in a normalised condition for comparison.<br/><br/>
