Abstract
A novel approach has been developed for the synthesis of (Fe,W)6C and (Fe,W)12C carbides from iron and tungsten powders via their wet mechanical alloying followed by compaction and annealing at 900 °C. It has been found that the compacted samples show the density of up to 12.5 g·cm−3, microhardness of up to 10GPa, and high wear resistance under abrasive wear and dry sliding friction against a steel disk. As for the level of the catalytic activity with respect to the hydrogen evolution reaction in sulfuric acid solution, the obtained carbides are between Fe3C and WC-6Co alloy.
