Method for making metallic cord |
摘要 |
A method for making a metallic cord made up of one or more metallic wires comprises: making at least two layers of at least two metallic elements including copper and zinc on the surface of a base wire; heating the layers to cause the metallic elements thermodiffusion to transform into a primary alloy layer; making a layer of copper on the primary alloy layer; drawing the wire provided with the primary alloy layer and outer copper layer into a metallic wire through dies so that the outer copper layer is diminished during passing through the dies, and a secondary alloy layer is formed as a result of transformation of the primary alloy layer and the outer copper layer which is caused by frictional heat during passing through the dies.
