(57) A steel wire rope for use in a drive system such as found on a sliding vehicle door
or window elevator is revealed. Particular about this rope is that it has a remarkable
corrosion resistance in combination with a reduced wear of guiding pieces around which
the wire rope is guided. The corrosion resistance is obtained by spreading magnesium
oxide particles over the zinc or zinc alloy coated steel wires and bringing those
particles in contact with the coating. The reduced wear is obtained by spreading fine
abrasive particles over the coating. The spreading and contacting can be achieved
by means of a liquid carrier such as an aliphatic mineral oil that is commonly used
as the lubricant for such steel wire ropes. The magnesium oxide ensures an equal or
better corrosion resistance even when reducing the thickness of the zinc coating.
Reducing the thickness of the zinc coating increases the strength of the steel wire
rope, while maintaining the diameter of the cord. The abrasive particles ensure a
polishing of the wire leading to a smoother surface and reduced wear of the guiding
pieces.
