Performance of segment in the natural stone sawing process is decreased due to various reasons such as; non-uniform distribution of diamond grits, contact of diamond grits to each other’s, segregation of uncoated diamond grits in metal matrix, wrongly selected type of metal powders and diamond grit size. 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. 

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.
