1. 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.
