Marine and coastal equipment is often exposed to harsh corrosive environments, where the corrosion resistance of product enclosures and fasteners directly affects the service life, safety and operational stability of the equipment. To effectively evaluate the corrosion resistance performance of related components and ensure the quality and reliability of products in marine service environments, the salt spray corrosion test has become a core quality inspection link. This test simulates the actual marine corrosive environment, focuses on testing the corrosion resistance of product enclosures and fasteners, provides scientific and reliable data support for product quality control, and lays a solid foundation for the stable operation of marine-related projects.
