“…SAW form when the desert becomes cooler, usually during the autumn and spring seasons; rising temperatures, humidity, and meteorological conditions influence the indoor environment of the electronics industry. The principal air corrodent encountered in Ensenada is the NaCl aerosols from the sea, in addition to CO, NO and SO 2 from traffic vehicles, power stations, and industrial and landfill emissions which increase atmospheric corrosivity [13,14].…”

“…The corrosion rates were determined by applying the gravimetric method according to ASTM G 31 standard method. In order to simulate controlled indoor conditions, the chamber was fabricated with precoated aluminum with a total volume of 0.1 m 3 and conditioned with two air inlet blinds coupled to metallic filters in order to permit the penetration of gases with the flow of air, to prevent the penetration of dust, and to avoid mistakes in the weight loss calculations [13,14]. The chamber was provided with metallic internal supports to hold the specimens; it was installed on the roof of an electronics manufacturing plant at 10 m above ground level [15,16].…”

Copper Corrosion by Atmospheric Pollutants in the Electronics Industry

Hydrogen sulphide (H2S) is considered one of the most corrosive atmospheric pollutants. It is a weak, diprotic, reducing acid, readily soluble in water and dispersed into the air by winds when emitted from natural, industrial, and anthropogenic sources. It is a pollutant with a high level of toxicity impairing human health and the environment quality. It attacks copper forming thin films of metallic sulphides or dendrite whiskers, which are cathodic to the metal substrate, enhancing corrosion. H2S is actively involved in microbially influenced corrosion (MIC) which develops in water, involving sulphur based bacteria, in oxidizing and reducing chemical reactions. H2S is found in concentrated geothermal brines, in the atmosphere of geothermal fields, and in municipal sewage systems. Other active atmospheric pollutants include SOX, NOX, and CO. This investigation reports on the effects of H2S on copper in microelectronic components of equipment and devices, with the formation of nonconductive films that lead to electrical failures.

“…Indeed, silver sulphide is formed when sulphur-containing compounds come in contact with silver but if halogens are present they can also react to form silver halides [39,[43][44][45][46] even though with different corrosion kinetics with respect to the sulphide formation. Silver sulphide follows a linear corrosion law while AgCl, characterised by a more protective corrosion layer, presents a parabolic behaviour [47].…”

“…Upon decomposition, these seaweeds emit substantial amounts of hydrogen sulfide (H 2 S) into the atmosphere. Hydrogen sulfide is recognized as a potent oxidizing agent for various metals and metal alloys [13][14][15]. The anaerobic decomposition of stranded seaweed produces sulfides [16], a process similarly observed in sargassum accumulations.…”

This article aims to investigate the atmospheric corrosion of carbon steel in a marine environment abundant in hydrogen sulfide (H2S) resulting from the decomposition of Sargassum seaweed. To accomplish this, four sites with varying degrees of impact were chosen along the coast of Martinique. The corrosion rates of steel were evaluated through mass loss measurements. After one year of exposure, the corrosion rates were notably high, particularly in atmospheres rich in Cl− ions and H2S, ranging from 107 µm to 983 µm. Complementing these findings, surface and product morphologies were characterized using scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). These analyses revealed a significant degradation of the corrosion surface in the most affected atmospheres compared to those unaffected by Sargassum seaweed strandings. Lepidocrocite (γFeOOH) was identified as the predominant product regardless of the exposure atmosphere. However, goethite (αFeOOH) was found to be present in atmospheres most impacted by H2S.
