摘要： The present invention provides an anti-corrosion composition for a metal surface, especially of pre-stressing steel, the anti-corrosion composition being thixotropic and comprising an organic component which is an oil, fat or wax. The anti-corrosion composition of the invention is characterized in that it is translucent and also comprises an indicator which responds to corrosion of the metal surface by changing its absorption spectrum in the region of ultra-violet, visible or infra-red light, in particular with a colour change. Further provided in accordance with the invention are a metal structure bearing the anti-corrosion composition of the invention, an apparatus on the metal structure, and a method for checking the metal structure.

摘要： [Problem] Remaining service life of a metal pipe suffering from creep damage is measured without scraping the surface of the metal pipe. [Solution] In a remaining service life evaluation method according to the present invention, the remaining service life of a metal pipe (1) suffering from creep damage is evaluated on the basis of a master curve that is prepared in advance. The master curve is prepared by performing an internal pressure creep test in a state in which a steel strip (2), made of a metal material having a thermal expansion coefficient and strength of the metal pipe or greater, is wrapped under tension around an outer peripheral face of a test piece (11) made of the same material and having the same inner and outer diameters as the metal pipe. The master curve indicates a relationship between a degree of deterioration of the steel strip and remaining service life of the metal pipe. To evaluate the remaining service life, a steel strip is wrapped around an outer peripheral face of the metal pipe under the same conditions as those during the internal pressure creep test. The degree of deterioration of the steel strip with the use of the metal pipe is then measured, and applied to the master curve.

摘要： A corrosion monitoring system (110) includes at least one corrosion sensor (100). The corrosion sensor (100) includes a metallic plug (104) having at least one opening, at least one ceramic sheath (106) in the opening of the metallic plug (104), and a plurality of probes (102). Each probe (102) has a central portion with a predetermined cross sectional area extending from the metallic plug (104). The ceramic sheath (106) electrically isolates each first end and each second end of the probes (102) from the metallic plug (104) and the other first ends and second ends. The probes (102) are sized to provide a range of predetermined cross sectional areas of the central portions. Such arrangement permits to extend the lifespan of the system since when one probe has been completely corroded, measurement can be switched to another probe having a higher cross sectional area and which is still operational.The corrosion monitoring system (110) also includes a resistance meter (112) measuring an ohmic resistance for at least one of the probes (102) and a computer (116) determining a corrosion rate by correlating a rate of change of the ohmic resistance to the corrosion rate of the probe (102). The corrosion monitoring system (100) is particularly suitable for real-time corrosion monitoring of components in the hot gas path of turbines.

摘要： When the resistance to sulfide stress corrosion cracking is evaluated by applying a constant load stress à (MPa) to a round bar tensile test specimen immersed in a test solution and checking whether failure occurs before a particular time passes, the round bar tensile test specimen including a parallel section, a shoulder section, and a grip section is used. In the round bar tensile test specimen, the shoulder section is formed by a curve having two or more radii of curvature, a radius of curvature R1 (mm) of a portion adjacent to the parallel section is 15 mm or more and satisfies (0.22à - 119) ‰¤ R1 ‰¤ 100, a length X1 (mm) of a portion of the curve having the radius of curvature R1 in a longitudinal direction of the test specimen satisfies X1 ‰¥ ˆš{(r/8) × (R1 - r 2 /4)} (r: radius (mm) of the round bar tensile test specimen in the parallel section), and the radius of curvature R1 is larger than other radii of curvature. Thus, even when the steel is a high-strength steel having a yield strength of 758 MPa or higher, the occurrence of the failure in the shoulder section is suppressed, and the resistance to sulfide stress corrosion cracking can be properly evaluated.
