Abstract
Thermal spray coating obtained from a thermal spray powder material containing at least one of Aluminum-containing particles, Magnesium-containing particles, and Titanium-containing particles mechanically alloyed to a transition metal. The coating includes Aluminum, Magnesium, or Titanium alloy portions alloyed to the transition metal. The thermal spray powder is obtained of Aluminum, Magnesium, or Titanium containing particles mechanically alloyed to a transition metal.
Claims28
A thermal spray coating, comprising:
- metal-containing particles mechanically alloyed to a transition metal by repeated cold welding, fracturing and re-welding, the metal-containing particles each comprising a core of at least one of Aluminum, Magnesium, and Titanium,
- wherein the cores are surrounded by the transition metal that is mechanically alloyed to the core by repeated cold welding, fracturing and re-welding, and
- wherein the thermal spray coating is formed by spraying a composition comprising at least one of:
- organic material blended, mixed, or clad with the metal-containing particles;
- or
- inorganic solid lubricant blended, mixed, or clad with the metal-containing particles.
A thermal spray powder comprising:
- metal-containing particles mechanically alloyed to a transition metal by repeated cold welding, fracturing and re-welding, the metal-containing particles each comprising a core of at least one of Aluminum, Magnesium, and Titanium,
- wherein the cores are surrounded by the transition metal that is mechanically alloyed to the core by repeated cold welding, fracturing and re-welding, and
- wherein the thermal spray coating is formed by spraying a composition comprising at least one of:
- organic material blended, mixed, or clad with the metal-containing particles;
- or
- inorganic solid lubricant blended, mixed, or clad with the metal-containing particles.
A method of making a thermal spray powder including at least one of Aluminum-containing particles, Magnesium-containing particles, and Titanium-containing particles, the method comprising:
- mechanically alloying a transition metal to metallic powder particles containing cores of at least one of Aluminum, Magnesium, and Titanium by repeated cold welding, fracturing and re-welding,
- wherein the cores are surrounded by the transition metal, which is mechanically alloyed to the cores by repeated cold welding, fracturing and re-welding, and
- wherein the thermal spray coating is formed by spraying a composition comprising at least one of:
- organic material blended, mixed, or clad with the metal-containing particles;
- or
- inorganic solid lubricant blended, mixed, or clad with the metal-containing particles.
