Abstract: Ni-1.5 wt.% C, Ni-1.5 wt.%C-14 wt.%Cr, and Ni-1.5 wt.%C-29 wt.%Cr alloy powders were low-pressure plasma sprayed to produce nickel-base composite deposits with dispersed carbide particles. The constituent of the as-sprayed deposit formed on a water-cooled substrate from the Ni-1.5 wt.%C alloy powder is a nickel phase that is supersaturated with carbon. The deposit heat-treated at 673 K in vacuum consists of a nickel phase, nickel carbide, and graphite. In the case of the Ni-1.5 wt.%C-14 wt.%Cr alloy powder, the as-sprayed deposit produced on a water-cooled substrate is made up of a nickel phase that is supersaturated with chromium and carbon, and subsequent heat-treatment of the deposit leads to the formation of chromium carbide and graphite. When the non-cooled substrate is used, the as-sprayed deposit consists of a nickel phase, chromium carbide, and graphite. The as-sprayed deposit formed on a non-cooled substrate from the Ni-1.5 wt.%C-29 wt.%Cr alloy powder is composed of a nickel phase, chromium carbide, and graphite.
