“…Analogous conclusions were drawn by Jiang et al [23] and Jikal et al [24] with regard to pitted high strength steel (HSS) wires. For the relevant case of high-strength bolts and bolted details, complying remarks were pointed out by Zampieri et al [25], Lachowiz et al [26], Li et al [27] and Jiang et al [28], which highlighted the influence of increased fretting wear on the fatigue life of corroded specimens, i.e., due to premature crack initiation at worn contact surfaces [25][26][27][28].…”

“…Compared with industrial atmospheric environment, high-strength bolts showed higher corrosion sensitivity in marine atmospheric environment, which led to bolt loosening and fatigue crack of bolt thread [15][16]. Therefore, the corrosive environment caused serious corrosion behavior to the raw materials of the steel bridge, which is one of the main factors affecting the performance degradation of the FHSB connection joints of steel structures [17][18][19]. In conclusion, due to different corrosive environments of the FHSB connection nodes of the steel bridge, their corrosion behaviors and corrosion products are also different, therefore, it is of great research value to study the characteristics of corrosion products of the nodes on the real bridge and influence factors in complex environmental corrosive conditions, such as wet, industrial and dust climates.…”

This paper analyzed the main diseases of the friction high-strength bolt (FHSB) joints in order to study the characteristics of the corrosion products of the joints in steel bridge and the influence factors. Seven representative FHSB connection pairs and eight steel plate samples were selected from the Dongying Shengli Yellow River Bridge, which has been in operation for 33 years. Then Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS) and X-Ray Diffraction (XRD) were used to analyze the microscopic morphology and chemical composition of the corroded surface of the samples. Finally, this paper discussed the relationship between the corroded sample surface and the environmental corrosion. The research results showed that construction quality problems, such as non-standard hole expansion, segmental slab joint dislocation and contact surface pollution, accelerated corrosion of the contact surface. With the increase of corrosion degree of joints, the contact surface of aluminum spraying layer gradually changed from a rugged and dense state to a smooth and porous powder state. With the corrosion of the steel plate substrate, the contact surface gradually changed from a fluffy stratified state to a surface bonding state. It was inferred that the friction coefficient of the FHSB connection node on the corroded aluminum sprayed contact surface first decreased and then increased. The corroded node samples detected not only a large number of S and Cl elements, but also the oxides of Mn, Si and other elements as well as FeS. It was speculated that node corrosion was also related to atmospheric (acid rain) and industrial dust and other corrosive environments. Almost all samples detected the component SiO2 of the Yellow River soil, as well as Mg, Ca, K, Na and other elements at the same time, which is basically consistent with the component elements of the Yellow River soil. Therefore, it was inferred that it was related to the inclusion of the Yellow River soil.

Therefore, the corrosive environment caused severe corrosion behavior in the raw materials of steel bridges, which is one of the main factors affecting the performance degradation of FHSB connection joints of steel structures [17][18][19]. In an effort to suppress steel corrosion, many researchers have reported various results annually on corrosion inhibitors, including their preparation or extraction, as well as the mechanism of classification and inhibition [20][21][22][23][24].…”

The contact surface corrosion of friction high-strength bolt (FHSB) joints was analyzed to examine the characteristics of corrosion products and influence factors in steel bridges. Samples were selected from the Dongying Shengli Yellow River Bridge, which has been in service for 33 years. Scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD) were utilized to analyze the microscopic morphology and chemical composition of the corroded surface of the samples. The study identifies that construction quality issues accelerate corrosion of the contact surface and that the contact surface of the aluminum spraying layer transforms from rugged and dense to smooth and porous as corrosion increases. The findings also suggest that the friction coefficient of the FHSB connection node initially decreases and then increases as the corroded surface changes. Corrosion products contained S, Cl, Mn, Si, FeS, and their oxides, indicating that atmospheric, industrial, and Yellow River soil environments contribute to joint corrosion. The study proposes sandblasting and coating the corroded contact surface and deck steel plate with inorganic zinc-rich paint to prevent media penetration and delay substrate corrosion. Adopting ultra-high-performance concrete (UHPC) as the deck structure is also recommended to reduce top plate tensile stress, deck cracking, and media invasion. This study provides insights into the characteristics and mechanisms of FHSB joint corrosion to aid the maintenance, repair, and protection of steel bridges.
