Paper Title:
Production of Stainless Cast Iron Base Deposits with Dispersed Titanium Carbide Particles by Plasma Spraying
  Abstract

Fe-C-Ti-Cr-Ni alloy powder in diameter of 32-53 μm made by argon atomization is low-pressure plasma sprayed to produce stainless cast iron base deposits with finely dispersed titanium carbide particles. The as-sprayed deposit formed on a water-cooled substrate consists of γFe, αFe, TiC and Cr3C2. Heat treatment of the as-sprayed deposit above 873 K results in the formation of Cr7C3. The fine precipitates of approximately 0.2 μm in the as-sprayed deposit formed on a water-cooled substrate are carbide. The as-sprayed deposit produced on a non-cooled substrate and deposits which are obtained by heat treatment of the as-sprayed deposit are composed of γFe, αFe, TiC, Cr3C2 and Cr7C3. As heat treatment temperature increases, carbide precipitates coarsen. The hardness of deposit decreases with increasing heat treatment temperature. The wear resistance of as-sprayed deposit formed on a non-cooled substrate was higher than that of the deposit heat-treated at 1273 K. The as-sprayed deposit and deposit heat-treated at 1273 K have higher wear resistance than a commercial stainless steel.
