“…The corrosion behavior of the welded joint of pipeline steel may be different from that of the base metal, especially the welding residual stress closely related to the welding process. Therefore, the earliest work in this area was research on welding residual stress, mainly studying postweld heat treatment and adjusting the welding process, so as to reduce welding residual stress and improve the corrosion resistance of the welded structure (Kse, 2020). After determining the corrosion system and corrosion environment of the base metal, the alloy composition and the content of the welding material are important factors that determine the composition, structure, and performance of the weld.…”

In order to find the low-alloy high-strength steel welded with the strongest corrosion resistance, the corrosion resistance of HSAL weld metal was studied by considering different alloy compositions. Corrosion resistance of alloy compositions of 460, 690, and 980 MPa was analyzed in an atmospheric environment and simulated seawater environment, respectively. The results of the corrosion weight gain test, weight loss test, and Kelvin probe test showed that the HSAL weld metal with 980 MPa alloy composition has the best corrosion resistance in an atmospheric environment. Through seawater immersion and electrochemical testing, it was found that the HSAL weld metal with 980 MPa alloy composition had good corrosion resistance in a simulated seawater environment, the HSAL with 690 MPa alloy composition had medium corrosion resistance, and the HSAL with 460 MPa alloy composition had the lowest corrosion resistance. The corrosion resistance of the weld zone is the best and that of the heat-affected zone is the worst; these findings may be helpful for research in related fields.

“…In addition to the investigation of DSS corrosion resistance (2205 alloy) in as built condition [31,32], many experimental studies focused on coating the biomaterial by the electrophoretic deposition of a hydroxyapatite/titania nanocomposite [16] and by electrical discharge [15] to enhance the DSS biological response and corrosion resistance. Kose et al [31] investigated the corrosion resistance and apatite formation on the surface of base and laser-welded AISI 2205 DSS implants in SBF for 1, 3, 7, 14, 21, and 28 days. The samples were laser-welded using the following values of laser power [W] and scanning speed [cm/min]: C1-3500 W, 90 cm/min; C2-3500 W, 270 cm/min; C3-4000 W, 90 cm/min, and C4-4000 W, 180 cm/min.…”

The austenitic stainless steels utilized in the production of osteosynthesis devices are susceptible to crevice corrosion. Several studies have compared the corrosive behavior of austenitic and duplex stainless steels (DSS), both of which are recognized as viable biomaterials for tissue engineering applications. All of the in vitro and in vivo studies on animals and clinical results reported to date indicate that austeno-ferritic duplex stainless steel can be recommended as a suitable alternative to ASTM F138 steel, since it is resistant to crevice corrosion in the human body and presents superior mechanical properties. The use of DSS for biomedical applications is still under discussion, mainly due to the lack of knowledge of its behavior in terms of device heating or induced movement when exposed to magnetic fields, a potentially harmful effect for the human body. As a breakthrough production technology, additive manufacturing (AM) has demonstrated significant benefits for the fabrication of metal devices with patient-specific geometry. Laser powder bed fusion has particularly been used to manufacture DSS-based components. A fine control of the processing conditions allows for an understanding of DSS microstructural evolution, which is essential for selecting processing parameters and estimating performance, including mechanical properties and corrosion resistance. Furthermore, scientific investigation is necessary for determining the relationships among material, process, and magnetic properties, in order to establish the underlying principles and critical responses. The purpose of this review is to highlight the key performances of DSS for biomedical applications and to point out the relevant role of advanced processing technologies such as additive manufacturing.

“…Figure 8 shows the potentiodynamic polarization curves of samples with different Y 2 O 3 addition amounts in NaCl solution with mass fraction of 3.5wt%. Thin chromium-oxide film is easily formed on the surface of 316 L austenitic stainless steel [29], which is present as a passivated zone in Figure 8. Previous studies have indicated the improvement in corrosion resistance with laser surface treatment of austenitic stainless steel [30].…”

Laser cladding technology is a surface modification technology emerging in recent years, and it is widely used in the marine engineering field. Since the structural steels used in marine engineering are mostly carbon steels, their wear resistance and corrosion resistance are poor. In this paper, 316 L stainless steel/TiC composite coatings with different Y2O3 addition amounts were fabricated on Q355B steel surface using the laser cladding technology, and the phase composition, microstructure, microhardness, wear resistance, and corrosion resistance of the coatings were investigated with an X-ray diffractometer (XRD), a scanning electron microscope (SEM), a digital microhardness tester, a friction and wear tester, and an electrochemical workstation. When Y2O3 is added, the crystals in the bottom part of the coating are basically broken and the organisation becomes more dense. When the Y2O3 addition amount is 2%, the hardness is highest, the frictional coefficient curve of the coating exhibits a stable descending trend, and the coating mass loss is the lowest. When Y2O3 is added at 1%, the dynamic potential polarisation curve shows high corrosion potential and low corrosion current density and exhibited the best performance in EIS. The added Y2O3 evidently improves the wear resistance and corrosion resistance of 316 L stainless steel/TiC composite coatings, and this provides a new possibility that a composite coating modified with rare earth oxide is used for repair of marine engineering structures.
