摘要:
A bi-metal medical guidewire with a core wire having a stainless steel proximal section and Nitinol distal section offers performance enhancements compared to guidewires made from either alloy alone. A solid-state, frictional welding or frictional joining process for Nitinol and stainless steel wires ranging in diameter from 0.013″ to 0.020″, without the need for tertiary metals, adhesive or ferrules is disclosed. The resulting frictional weld joint strength is approximately 80% of the tensile strength of the raw Nitinol wire with excellent bending properties.
