“…The antibacterial activity and biofilm-inhibition efficiency of Cu-LASS against P. aeruginosa was as high as 93.6% and 36.2%, respectively, after a 14-day incubation. The XPS indicates Cu oxides formed in the corrosion product layer, which can be explained by the following reactions (Liu et al , 2019): …”

“…The released Cu ions from copper-rich phases could inhibit the attachment of P. aeruginosa biofilms through diverse ways such as inhibit cell division, oxidize proteins and degrade DNA and cytoplasm, leading to cell death (Xu et al , 2016). Furthermore, Cu ions may influence the structure and function of enzymes (Guo et al , 2017; Liu et al , 2019).…”

Purpose Low-alloy structural steels (LASS) face severe microbiologically influenced corrosion (MIC) in their service environments. To mitigate this issue, Cu is often used as an alloying element owing to its intrinsic antimicrobial activity. However, the antibacterial performance and biofilm resistance of Cu-containing LASS (Cu-LASS) are still unclear. This study aims to analyze the effect of Cu addition to 420 MP LASS on its MIC by the Pseudomonas aeruginosa biofilm. Design/methodology/approach Scanning electron microscope, confocal laser scanning microscope and X-ray photoelectron spectroscopy were used to analyze the surface morphology and composition of corrosion products. The antibacterial activities of Cu-LASS were analyzed by the spread-plate method. In addition, electrochemical analysis was conducted to characterize the corrosion behavior of the produced alloy. Findings Bacterial analysis and morphological observation confirmed a reduced sessile cell count and inactivation of the P. aeruginosa biofilm on the surface of Cu-LASS coupons. Electrochemical measurements showed that Cu-LASS exhibited large polarization and charge-transfer resistances, which indicated excellent MIC resistance. This significantly enhanced resistance to MIC could be explained by the synergistic effect of released Cu2+ from the Cu-LASS surface and immediate contact to Cu-rich phase in the surface and the release of Cu2+ ions from the Cu-LASS surface. Originality/value The effect of Cu addition on the MIC resistance and antibacterial performance of LASS is seldom reported. It is necessary to investigate the corrosion resistance of Cu-LASS and clarify its antibacterial mechanism. This paper fulfills this need.

“…This was attributed to the copper-rich phases on the surface and to the release of copper ions, which will confer strong antibacterial properties to the alloy, inhibiting P. aeruginosa attachment [ 58 ]. Moreover, Liu, et al [ 59 ] evaluated the corrosion resistance of 2205–3% Cu DSS against Acetobacter aceti biocorrosion. The results demonstrated effective biofilm inhibition and reduction in pitting depth in copper-2205 DSS in comparison to copper-free 2205 DSS [ 59 ].…”

Biofilms are structures comprising microorganisms associated to surfaces and enclosed by an extracellular polymeric matrix produced by the colonizer cells. These structures protect microorganisms from adverse environmental conditions. Biofilms are typically associated with several negative impacts for health and industries and no effective strategy for their complete control/eradication has been identified so far. The antimicrobial properties of copper are well recognized among the scientific community, which increased their interest for the use of these materials in different applications. In this review the use of different copper materials (copper, copper alloys, nanoparticles and copper-based coatings) in medical settings, industrial equipment and plumbing systems will be discussed considering their potential to prevent and control biofilm formation. Particular attention is given to the mode of action of copper materials. The putative impact of copper materials in the health and/or products quality is reviewed taking into account their main use and the possible effects on the spread of antimicrobial resistance.

“…The austenite initially precipitates at the grain boundaries at the time of cooling, then at the Widmanstädter plates, and eventually as intergranular precipitates [2]. The duplex steel exhibits excessively ferritic microstructures with deteriorated welding metal properties during the autogenous laser welding phase [3][4][5][6][7][8][9], and is thus avoided. The DSS does not have sufficient time to form an austenitic phase during laser welding in the case of low heat input and rapid cooling.…”

Welding parameters can greatly affect the final product. In this study, there was a variation given on the pulse energy, i.e., heat input parameters. The microstructure was analyzed and presented in relation to the efficiency of corrosion. The microstructural study showed the changes of the fusion zone (FZ) and the heat-affected zone (HAZ) with an increase in pulse energy. The development of a prominent austenite process on the weld material had a prolonged effect on its corrosion resistance property. Electrochemical impedance spectroscopy (EIS) and potentiodynamic measurements were used to test the electrochemical activity of laser-weld 2205 duplex stainless steel in an aqueous 3.5% NaCl solution. Finally, the findings of the EIS analysis were supported by Raman spectroscopy. Based on the obtained results, the 2205 duplex stainless steel (DSS) weld obtained at a higher pulse energy showed higher corrosion resistance than the welded sample obtained at a low pulse energy. The impedance spectroscopy confirmed a smooth surface property with an increase in the pulse energy and the presence of an oxide layer, a finding also confirmed by the Raman spectroscopy measurements.
