A thermal spray powder consists of nickel, chromium and carbon. The chromium consists of a first portion and a second portion, the nickel being alloyed with the first portion in an alloy matrix. The second portion and the carbon are combined into chromium carbide substantially as Cr,C,or Cr,C,or a combination thereof, with the chromium carbide being in the form of precipitates between 0.1 &mgr;m and 5 &mgr;m distributed uniformly in the alloy matrix.

Method for preparing a thermal spray powder of chromium carbide and nickel chromium

A thermal spray powder consists of nickel, chromium and carbon. The chromium consists of a first portion and a second portion, the nickel being alloyed with the first portion in an alloy matrix. The second portion and the carbon are combined into chromium carbide substantially as Cr.sub.3 C.sub.2 or Cr.sub.7 C.sub.3 or a combination thereof, with the chromium carbide being in the form of precipitates between 0.1 .mu.m and 5 .mu.m distributed uniformly in the alloy matrix.
