Definitions of throwing power on the Web:

The ability to effect satisfactory coverage in recessed or blind (hole) areas of a part being plated.
www.wmrc.uiuc.edu/main_sections/ ... inishing/appxa1.htm

The ability of electro-deposited coatings to cover interior surfaces.
www.etfinancial.com/coatingsgloss.htm

(1) The relationship between the current density at a point on a surface and its distance from the counter electrode. The greater the ratio of the surface resistivity shown by the electrode reaction to the volume resistivity of the electrolyte, the better is the throwing power of the process. (2) The ability of a plating solution to produce a uniform metal distribution on an irregularly shaped cathode. Compare with covering power.
