Propellers can experience pitting and erosion, affecting their hydrodynamic performance and efficiency. Marine engines and other machinery may suffer from internal corrosion, leading to decreased reliability and potential breakdowns at sea, which can have severe consequences for both safety and operational costs.

2.3 Electronic Devices

Although not as visibly affected as larger mechanical components, electronic devices are also susceptible to salt spray corrosion. Printed circuit boards (PCBs) and their components, such as connectors, capacitors, and resistors, can be damaged. Corrosion on the PCB traces can cause short circuits or open circuits, leading to malfunctioning or complete failure of the device. Outdoor electronic enclosures, such as those used in telecommunications and power distribution, can also be corroded by salt spray, allowing moisture to penetrate and damage the internal electronics, compromising the functionality and reliability of the equipment.

2.4 Architectural Hardware

Doors, windows, and other architectural hardware in coastal regions are prone to salt spray corrosion. The corrosion can cause the metal surfaces to become discolored, pitted, and weakened. This not only affects the aesthetic appeal of the building but also reduces the durability and security of the hardware. For example, corroded door hinges may not function properly, and window frames may become leaky, allowing water and air to penetrate, leading to further damage to the building’s interior.
