Adhesion and corrosion properties of a new NiZn/ZnCo-coated steel tire cord

A new steel tire cord is described which is coated with an electrodeposited coating consisting of a base layer of 1.5 μm Zn-1%Co and a top layer of 0.5 μm Ni-20%Zn. This coating is proposed to replace the conventional brass coating. This new cord has superior corrosion resistance and aged adhesion r...

Zusammenfassung:	A new steel tire cord is described which is coated with an electrodeposited coating consisting of a base layer of 1.5 μm Zn-1%Co and a top layer of 0.5 μm Ni-20%Zn. This coating is proposed to replace the conventional brass coating. This new cord has superior corrosion resistance and aged adhesion retention properties which are described in this paper. The phase structure and composition of the coating before, during and after wire drawing were studied by X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray analysis.
