摘要：
A highly corrosion and abrasion resistant coating combination for high precision metal tubing comprises a passivation layer applied to the tubing and a thermoplastic jacket extruded onto the passivated tubing. In an embodiment, the passivation layer is formed by electropolishing the exterior surface of the tube to remove impurities in an upper layer of the tube.
