A free-flowing self-bondable flame spray powder derived from an atomized alloy powder is provided in which the particles are characterized by aspherical shapes and have an average particle size within the range of about plus 400 mesh to minus 100 mesh. The aspherically shaped powder is further characterized by a specific surface of about 180 cm.sup.2 /gr and higher and has a composition consisting essentially of a solvent metal of melting point in excess of about 1100.degree. C. whose negative free energy of oxidation ranges up to about 80,000 calories per gram atom of oxygen referred to 25.degree. C. The solvent metal contains at least one highly oxidizable solute metal in an amount of at least about 3% by weight, the oxidizable metal having a negative free energy of oxidation of at least about 100,000 calories per gram atom of oxygen referred to 25.degree. C.

Flame spray powder

A flame spray powder mix is provided for producing coatings on metal substrates, such as substrates of steel, cast iron, non-ferrous metals, among other substrates, the powder mix comprising agglomerates of a metallo-thermic heat generating composition (i.e., a thermic composition, such as an alumino-thermic composition) mixed with at least one coating material, such as metal and/or non-metal coating materials.

Metallo-thermic powder

A flame spray powder mix is provided for producing coatings on metal substrates, such as substrates of steel, cast iron, non-ferrous metals, among other substrates, the powder mix comprising agglomerates of a metallo-thermic heat generating composition (i.e., a thermit composition, such as an alumino-thermic composition) mixed with at least one coating material, such as metal and/or non-metal coating materials.
