WC THERMAL SPRAYED ROLL HAVING SUPERIOR CORROSION RESISTANCE AND WEAR RESISTANCE

摘要

PURPOSE: A WC thermal sprayed roll having superior corrosion resistance and wear resistance is provided which reduces repairing cost and improves productivity by simultaneously satisfying corrosion resistance and wear resistance. CONSTITUTION: The WC thermal sprayed roll having superior corrosion resistance and wear resistance is characterized in that it is manufactured by performing metal based high corrosion Cr-Fe-Ni-Mo-B based thermal spray coating on a matrix metal, thereby forming first layer, and performing WC-Co-Cr based WC thermal spraying on the first layer, thereby forming second layer.
