Diamond is the most suitable abrasive for manufacturing natural stones. There are three types of diamond tools; sintering, electroplating, and brazing. Active brazing method offers high bonding strength of brazed diamond grits, and large chip storage space of abrasive tools. The main reactive element systems suitable for brazing diamond are Ti and Cr. In this study, the combination of the active brazing and PVD coating was investigated in Ni-Cr and Ti alloy system. Microstructures of the samples were determined by SEM and XRD analysis. In order to examine the mechanical properties, the hardness was measured by indentation method, micro-scratch analyzes and the wear tests were carried out. In the wear tests, natural stone was used as abrasive. No water was used during the test, and the resistance of the coating against heating was observed. Results showed the active brazing-PVD coating samples have high mechanical properties than active brazing samples.
