Pipe Threaded Joint, And Method For Producing Pipe Threaded Joint
Abstract: The present invention provides a pipe treaded joint and a method for producing the same. The pipe threaded joint is provided with a pin (4), a box (5), and a Zn-Ni alloy-coated layer (6). The pin (4) has a pin-side contact surface (40) including a pin-side threaded portion (41). The box (5) has a box-side contact surface (50) including a box-side threaded portion (51). The Zn-Ni alloy-coated layer (6) is disposed on at least one among the pin-side contact surface (40) and the box-side contact surface (50). The Zn-Ni alloy-coated layer (6) is composed of Zn, Ni, trace Cr, and impurities. The content of trace Cr in the Zn-Ni alloy-coated layer (6) is at least 5.0×10 counts/second in terms of Cr intensity as measured by secondary ion mass spectrometry using O2+ as an ion source.
