The present invention provides a steel wire rod including a lubricating coating film, which can reconcile workabilities such as wire drawability, spike property, ball ironing property and film removability, and corrosion resistance such as long-term rust prevention property. The steel wire rod includes a lubricating coating film on a surface, wherein the lubricating coating film contains a water-soluble silicate and a water-soluble tungstate, a mass ratio of water-soluble tungstate/water-soluble silicate being in a range of 0.7 to 10, and contains no phosphorus

Coatings for medical devices having selectable levels of durability and lubricity are disclosed. The coatings include polymeric material components, the characteristics and relative amounts of which can be selected to provide target levels of durability and lubricity. Methods of making the coatings for medical devices are also disclosed.
