Zusammenfassung:	An electrogalvanized coating for improved resistance welding of galvanized steel parts or sheets includes particles of a metal phosphide, and preferably ferrophosphorus particles, having a particle size of 0.1 to 30 mu m. The coating can also include up to 40% by weight of the metal phosphide of an additional metal such as nickel, tin, aluminum or lead, which can be incorporated in the coating as discrete particles or deposited onto the surface of the metal phosphide particles.
