Abstract
Tungsten-based coatings have attracted considerable interest in recent years for industrial applications because
of superior wear resistance. In this study, the W-Co oxide dispersion strengthened (ODS) coating on stainless
steels by mechanical alloying (MA) has been investigated. The different reinforced particles (Y2O3, TiC) have
been introduced to the W-Co coating layer as dispersion strengthening during mechanical alloying. The results
showed that the formation of the (W,Co)C, Co7W6 and Co3W phases was generated after a long milling duration.
The use of Y2O3 dispersed particles in the coating layer demonstrated homogenous distribution of microstructure
and an increase of mechanical properties. However, the coating with TiC reinforcement has a significant change
in distribution of the microstructure and composition and formed voids or micro-cracks, which decrease densification
and hardness of the coating materials. The W-Co ODS coating by mechanical alloying is one of the most
promising coating methods for enhanced wear resistance on stainless steels.
