Abstract: (26 Views)
In this study, a hybrid composite (Ti-10Mo-X (TiC & TiB2)) fabricated using the Spark Plasma
Sintering (SPS) method at a sintering temperature of 1150° with a varied range of the ceramic
reinforcement amounts (0.5, 1, 2, and 4 weight percent). For this purpose, the microstructure, phase
structure, and corrosion behavior were evaluated using optical microscopy, scanning electron
microscopy, XRD patterns, and potentiodynamic polarization tests. The results indicate that increasing
the amount of ceramic reinforcements from 0.5 to 4 percent decreases the residual molybdenum,
whereas the beta phase increases. Moreover, the porosity around the molybdenum decreases by
increasing the reinforcement particles, and the Ti-10Mo composite containing 4 weight percent of the
reinforcement exhibits the lowest porosity. The increase in the beta phase and the reduction in porosity
cause an improvement in corrosion behavior. The lowest and highest corrosion resistance is observed
for the samples 1150-0.5 with the highest corrosion current density of 1.25 μA/cm² and 1150-4 with
the lowest corrosion current density of 0.22 μA/cm², respectively. The corroded surface of 1150-4 is
uniform compared to the others.
