Abstract
A brass layer is formed on a steel wire, and an Ni layer is formed on the brass layer. Then, the steel wire is drawn through a die, and the brass layer and Ni layer are mixed into an alloy coating layer. In the coating layer, the closer to its surface the higher the Ni content. According to the method, a rubber-reinforcing steel wire can be produced which shows improved wet adhesive property to rubber, without degrading drawability.
