AN INVESTIGATION ON WEAR PERFORMANCES OF DIAMOND SAWBLADES: EFFECT OF PHYSICO-MECHANICAL PROPERTIES.

In this study, wear performance of diamond sawblades in sawing of rocks was experimentally investigated. Specific wear (SW) was selected as the criteria for sawblade wear performance and the SW was correlated with the rock physico-mechnical properties. Surface morphologies of wearing segments were also examined using scanning electron microscope (SEM) images. As a result, the microhardness was determined as the dominant physico-mechanical rock properties affecting the SW. Additionally; emerging, fractured, polished and pull-out crystals were observed in the wearing surfaces of the diamond segments. [ABSTRACT FROM AUTHOR]
