Abstract
This paper reports, the effect of reinforcement particle on the density, hardness, microstructure and corrosion characteristics in 3% NaCl solution of Iron (Fe) based composites fabricated through powder metallurgy. Optical microscope is used to microstructures characterized. Phase and microstructure of sintered specimen have been studied under XRD and Optical microstructure respectively. Density of Fe–SiC–ZrO2 hybrid composite decrease from 7.847 to 3.794 g/cm3 due to the addition of ceramic materials. The hardness of Fe–SiC–ZrO2 increased compared to base material from 327.4HV to 477HV for iron and composites respectively due to the addition of hard ceramics reinforcement. It was found that the corrosion behavior of reinforced Fe matrix improved due to the good corrosion resistance properties of reinforce materials.
