The aim of this experimental work is to prevent the clustering of diamond grits in segment production and to improve the sawing performance of segment in terms of microstructure, density, hardness and wear properties by using metal coated diamond grits. Three types of diamond segments (A: Commercial segment, B: Diamond with coated segment, E: segment without diamond) were produced in different compositions by powder metallurgy (P/M) and each one of the segment sample was sintered at three different temperatures (800, 900, 1000 °C) holding fifteen minutes under vacuum by hot pressing method.  </div> <div style="text-align:justify;">The highest hardness and wear resistance have been determined in B type sample sintered 900 oC. The phases formed in the microstructures were analyzed using SEM, EDS techniques and mapping.  Fractured surfaces and wear surface were examined by scanning electron microscopy and the fracture, wear mechanisms were evaluated. </div> <div style="text-align:justify;"> <br /> </div> </div> <p> </p> <p class="MsoNormal" style="margin-bottom:.0001pt;line-height:normal;"> <span lang="en-gb" style="font-size:8pt;font-family:’Times New Roman’, serif;" xml:lang="en-gb"> </span> </p> <p>  </p> <p class="MsoNormal" style="margin-bottom:.0001pt;line-height:normal;"> </p> <p class="MsoNormal" style="margin-bottom:.0001pt;line-height:normal;"> <b> <i> <span lang="en-gb" style="font-size:8pt;font-family:’Times New Roman’, serif;" xml:lang="en-gb">Keywords: </span> </i> </b> <i> <span lang="en-gb" style="font-size:8pt;font-family:’Times New Roman’, serif;" xml:lang="en-gb">  </span> </i> <i style="font-size:.9em;"> <span lang="en-us" style="font-size:8pt;font-family:’Times New Roman’, serif;" xml:lang="en-us">Mechanical Properties,  </span> </i> <i style="font-size:.9em;"> <span lang="en-us" style="font-size:8pt;font-family:’Times New Roman’, serif;" xml:lang="en-us">Metal Coated Diamond; Microstructure,   </span> </i> <i style="font-size:.9em;"> <span lang="en-us" style="font-size:8pt;font-family:’Times New Roman’, serif;" xml:lang="en-us">Powder Metallurgy,  Segment,  Wear </span> </i> </p> <p> <i> </i> </p> <i> </i> <p> <i> </i> </p> <i> </i>}, number={1}, publisher={Niyazi ÖZDEMİR}
