Claims
- 1. A resistance welding electrode having improved resistance welding characteristics, said electrode having a coating comprising a binder and a pigment, said pigment comprising at least one metal phosphide selected from the group consisting of iron, nickel, cobalt, tin, copper, titanium, manganese, molybdenum, tungsten, vanadium, tantalum, and mixtures thereof.
- 2. The electrode of claim 1 wherein the metal phosphide is ferrophosphorus.
- 3. The electrode of claim 1 wherein the pigment comprises particles having an average size within the range of about 0.1 to about 30 microns.
- 4. The electrode of claim 1 wherein the pigment also contains up to about 40% by weight of particles of a metal selected from the group consisting of tin, aluminum, lead, and mixtures thereof.
- 5. The electrode of claim 4 wherein the metal particles have an average size within the range of about 0.1 to about 30 microns.
- 6. The electrode of claim 1 wherein the ferrophosphorus particles are coated with a layer of a metal selected from the group consisting of tin, aluminum and lead.
- 7. The electrode of claim 1 which contains an intermediate layer of a metal selected from the group consisting of iron, nickel, cobalt, silver, manganese, vanadium, molybdenum and gold.
