Hydrothermal carbon effect on iron matrix composites produced by powder metallurgy

In this work, hydrothermal carbons (HTC) were obtained from glucose at 200 °C for 30 h. HTC and its calcinated product (HTC*) were added to pure iron powder with different ratios (0.25, 0.50 and 0.75 wt%) to obtained HTC reinforced iron composites by powder metallurgy. To our knowledge, this is the...

Description
Summary:In this work, hydrothermal carbons (HTC) were obtained from glucose at 200 °C for 30 h. HTC and its calcinated product (HTC*) were added to pure iron powder with different ratios (0.25, 0.50 and 0.75 wt%) to obtained HTC reinforced iron composites by powder metallurgy. To our knowledge, this is the first study that investigates the effect of HTC on iron matrix composites. Microstructure, hardness, compression and corrosion behaviors of composites were investigated. According to the results, mechanical properties of composites were enhanced with the increasing of HTC/HTC* amount. However, high corrosion resistances were gained with the using of the low amount of HTC (0.25 and 0.50 wt%) and HTC* (0.25 wt%). [Display omitted] •HTC–iron composites were produced by powder metallurgy.•Mechanical properties of composites were improved with the increasing of HTC/HTC* amount.•Low amount of HTC/HTC* in iron matrix was positively effective on corrosion rate.
