Resumo

In this study, samples prepared by pressing iron-based powder mixtures were divided into two different groups; sintering and boriding processes were applied in two steps in some of the samples, and in a single step in some of them. Sintering and boriding processes were applied at 950, 1000 and 1050°C for 2 hours. Various properties of borided and unborided samples in the first group and borosintered samples in the second group were compared. The microstructure in the samples was examined by optical microscope and SEM. Elemental analysis was performed by EDX. Phases formed as a result of boriding were detected by XRD. Surface roughness, microhardness measurements and wear tests were conducted on the samples. In the samples produced by powder metallurgy, the specifications of the structures formed as a result of first sintering and then boronizing process were similar. In both cases, the microhardness values of the material increased and wear-resistant structures were formed. It has been observed that the properties of the resulting structures show some changes depending on the temperature.
