Abstract

High chromium Fe-Cr-Mo-P-C amorphous coating films containing up to about 35 at% Cr having high hardness and high corrosion resistance have been produced by a newly developed thermal spraying technique. In order to control the temperatures of the powder particles in the flame spray and the substrate, a cylindrical nozzle, with external cooling nitrogen gas, was mounted to the front end of the thermal spraying gun. Fe₇₀Cr₁₀P₁₃C₇ and Fe₃₈Cr₃₅Mo₇P₁₃C₇ films with various external cooling gas velocities between 20 m/s and 40 m/s exhibited entire amorphous structure without oxides and/or unmelted powder particles. High corrosion-resistance of the Fe₃₈Cr₃₅Mo₇P₁₃C₇ amorphous coating film was observed in immersion tests using 35% hydrochloric acid.
