摘要： The invention concerns a threaded portion of a tubular element for a threaded tubular connection hiving an axis of revolution, the portion comprising a threading extending over its outer or inner peripheral surface, and a first sealing surface on the peripheral surface, the first sealing surface being capable of producing metal-metal interference with a corresponding second sealing surface belonging to a complementary threaded portion of a tube. The threading and the first sealing surface are coated with a metallic anti-corrosion and anti-galling layer wherein zinc (Zn) is tie major element by weight.
