With this aim powder provided from Elazig Ferro-Chromium Plant was mixed with iron powders having 2 %Co and then 2 %Ni, in proportions of 5, 10, and 20 percent. This mixtures were compacted under a load of 18 ton and sintered at 1100°C for 60 minutes. The composites produced were diffusion-bonded with AISI 1010 rectangular bars under bonding pressures of 2,5 MPa in 60 minutes. The bonding interface of the diffusion couples (AISI 1010-Cornposite) were examined with optical microscope, EDS, SEM and the hardness distributions were determined with Vickers Hardness Scale using a load of 3 Kg.VI As a result it was found that wear - resistance plates could be produced using ferro-chromium powder (Yıldırım, 1999) and these plates could be bonded with low C steels safely with diffusion bonding. n In the first chapter of the study, the subject was introduced, the powder metallurgy, ferro-chromium, solid-state boding methods in were discussed in the second, third and fourth chapters respectively. In the fifth chapter the experimental studies, in the sixth chapter the results of experiments were given. In the seventh and final chapter, the condusions and recommendations were presented. ©OKÛMANTASYON MERKEZÎ
