The substrate nickel plating layer is a nickel metal plating layer, a nickel-boron plating layer, or a nickel-cobalt plating layer.

The outer surface of the cover is covered by a nickel covering.

The metal core pattern (10) is melted out of the nickel plating to provide a nickel liner core (16).

The wire (10) has a steel core (12), a nickel sub-coating (14) and a zinc or zinc alloy top coating (16) above the nickel sub-coating.

The electrically conducting material includes nickel coated particles having a coating of silver or gold over the nickel coat and/or gold or silver coated nickel particles.

Gold plating, tin plating, tin alloy plating, or nickel plating (23) is applied to the upper surface of the each columnar terminal (14).

The invention is directed to a nodular nickel boron coating having lubricating properties.

The tubing material includes a stainless steel sheet metal (12) having a nickel or nickel alloy coating.

The use of the nickel sub coating allows to decrease the thickness of the top coating without decreasing the corrosion resistance.

The nickel coating efficiently when the surface on which the nickel coating is applied, no pores.

Nickel-coated polyaramide textile material have surprisingly exceptional flame resistance.

The inner edge of the nickel-plating coating is positioned inside the joining sections.

The average thickness of the nickel coating layer is not less than 0.5 μm and not more than 5 μm, and the ratio of the nickel coating layer relative to the positive electrode plate is not less than 30% by weight and not more than 80% by weight.

A wire (10) has a steel core (12), a nickel sub coating (14) and a zinc or zinc alloy top coating (16).

Tin plating, tin alloy plating, or nickel plating (25) is applied to the lower surface of the each columnar terminal (14) projected from the sealing resin (17).
