Microstructure, wear and corrosion properties of NiB-TiC composite materials produced by powder metallurgy method
In this study, NiB-TiC composite materials were produced using powder metallurgy. In the Ni-TiC-B powder mixture, TiC was fixed at a rate of 5 %, 5, 10 and 15 % boron was added and mechanical alloying was carried out. The prepared powder mixtures were cold pressed under pressure of 400 MPa...

| Summary: | In this study, NiB-TiC composite materials were produced using powder
metallurgy. In the Ni-TiC-B powder mixture, TiC was fixed at a rate of 5 %,
5, 10 and 15 % boron was added and mechanical alloying was carried out. The
prepared powder mixtures were cold pressed under pressure of 400 MPa and
sintered in an argon atmosphere at 800°C for 2 hours. Microstructure, phase
formation, hardness, wear and corrosion properties of the samples were
investigated in detail. Scanning electron microscopy (SEM) was used for
microstructure analysis and X-ray diffractogram (XRD) was used for phase
formation detection. The hardness measurements of the samples were measured
by a microhardness measuring device. Densities of the samples were
determined by Archimedes' principle. The corrosion tests were performed
potentiodynamic polarization curves of the composite materials in 3.5 % NaCl
solution. Wear tests were carried out the composite materials under a load
of 10 N. Results showed that by increasing the amount of B, the wear and
corrosion resistance increased. |
