Abstract
A thermal spray particle is substantially spherical, and contains iron and aluminum. An amount of aluminum contained in the thermal spray particle is in a range of 32 wt % to 48 wt %. The thermal spray particle includes a first region, in which a concentration of aluminum is in a range of 22 wt % to 37 wt %; and a second region, in which a concentration of aluminum is in a range of 40 wt % to 50 wt %.
Claims21
A thermal spray particle, wherein:
- the thermal spray particle is substantially spherical and contains iron and aluminum,
- an amount of the aluminum contained in the thermal spray particle is in a range of 32 wt % to 48 wt %, and
- the thermal spray particle includes
- a first region in which a concentration of the aluminum is in a range of 22 wt % to 37 wt %;
- a second region, in which a concentration of the aluminum is in a range of 40 wt % to 50 wt %;
- the first region and the second region are arranged in a patchy manner;
- precipitates are composed of an oxide of aluminum or a composite oxide of aluminum and iron;
- precipitates are distributed in a substantially ring shape around the center of the thermal spray particle, and
- the precipitates are acicular or spherical oxides as having a maximum dimension in a range of 0.1 μm to 2 μm are intermingled in the thermal spray particle.
