Thermisches Sprühpulver aus Wolframcarbid und Chromcarbid

摘要

A thermal spray powder is formed as a mixture of tungsten carbide granules and chromium carbide granules. The tungsten carbide granules each consists essentially of tungsten carbide bonded with cobalt, and the chromium carbide granules each consists essentially of chromium carbide bonded with nickel-chromium alloy. The powder may be asmixed with self-fluxing alloy powder. The powder preferably is sprayed with a high velocity oxygen-fuel thermal spray gun.
