Abstract
Abstract WC-Cr3C2-Ni thermal spray coatings was applied on the surface of low carbon steel (AISI 1018) using high-velocity oxy-fuel (HVOF) process. The base metal, coating powder and coated materials were analyzed using scanning electron microscope. Water-jet erosion test (WJET) was used to test the mass loss of the samples with different process parameters such as impingement angle, water jet velocity, erodent discharge, and stand-off distance. As results lower mass loss was observed for the selected process parameters. Pitting corrosion test reveals that better corrosion resistance can be achieved for the low carbon steels by WC-Cr3C2-Ni powder coating.
