What is a salt spray test?

Most components on military products require suppliers to do salt spray tests before they leave the factory, including RF cable assemblies and electrical connectors. The purpose is to ensure the reliability of the product and its service life.

Corrosion is the destruction or deterioration of a material or its properties caused by the action of the environment. Most of the corrosion occurs in the atmospheric environment, the atmosphere contains oxygen, humidity, temperature changes and pollutants and other corrosive components. Salt spray corrosion is one of the most common and destructive atmospheric corrosion. The salt spray here refers to the atmosphere containing chloride, which is mainly composed of chloride salts in the ocean.-- Sodium chloride, which mainly comes from the sea and inland saline areas. The corrosion of salt spray on the surface of metal materials is caused by the electrochemical reaction between the oxide layer and the protective layer on the surface of the metal and the internal metal. At the same time, the chloride ion contains a certain hydration energy, easy to be adsorbed on the metal surface of the pores, cracks and replace the oxygen in the chloride layer, the insoluble oxide into a soluble chloride, so that the passive surface into a live wave surface. Cause the product extremely bad adverse reactions.
