    摘要: A galling-resistant threaded tubular component for drilling or operating hydrocarbon wells includes at one of its ends a threaded zone produced on its external or internal peripheral surface depending on whether the threaded end is male or female in type, with at least one portion of the threaded zone being coated with a dry film with a crystalline structure with a high specific surface area principally constituted by one or more mineral salts which are not reactive towards metals, and a process for coating such a component using a dry mineral film with a crystalline structure having a high specific surface area principally constituted by one or more mineral salts which are not reactive towards metals.
