Two kinds of WC cermet coatings were prepared on Q345A steel substrate by using high-velocity oxy-fuel spraying technique. The friction and wear behavior and comprehensive properties of the cermet coatings were evaluated. And the applicability of the cermet coatings was explored in relation to their application at a cold rolling line of Baostcel Corporation. Results indicate that the as- sprayed WC cermet coatings can be well used to replace eleetroplated hard Cr coating for cold rolled rollers, and they may be extended to other relevant production lines in iron and steel factory as well.
