See also Bonding Force, and Ionic Bond. A thermal spraying process variation in which the metallic material to be sprayed is in the molten condition. A thermal spraying process in which a nontransferred arc is utilized as the source of heat that ionizes a gas which melts and propels the coating material to the workpiece. Material manufactured into finely divided particles. A nonstandard term for powder flame spraying.
Examples are inert gases, combusted fuel gases, hydrogen and vacuum.
A method of surface roughening in which a revolving roughening tool is pressed against the surface being prepared, while either the work or the tool, or both, move. Those materials that exhibit the characteristics of forming a metallurgical bond with the substrate in the as-sprayed condition. These alloys contain boron or silicon, or both, as fluxing agents. Protective gas used to prevent or minimize atmospheric contamination. See also Protective Atmosphere.
