Even today, corrosion persists to be a major problem in many industries. Salt spray testers, or salt fog chambers, are highly important when testing the material for usage in such conditions by measuring its strength with regard to sustaining the corrosive atmosphere. The corrosion tester produces a simulated environment with fast-tracked acceleration of corrosion; therefore, one is sure products made from materials would last a long time without failures.

Salt Spray Chamber Working

The salt fog test chamber is a high-end corrosion testing machine, designed from precise components to achieve trustworthy testing. The key components in it include:

  • Atomizing Nozzle: The saline solution is atomised to produce a fine mist that ensures uniform deposition on the test specimens.

  • Chamber Environment: Heaters and controllers are incorporated to provide a controlled temperature and humidity environment.

  • Solution Reservoir: The saline solution, a 5% NaCl solution, is prepared as per the standards of ASTM B117.

  • Air Saturator: Preliminary heating up of the pressurised air before atomising, which allows for the appropriate formation of salt mist.

Process Operation

In salt spray equipment, the process operation is strictly a balance between chemical and mechanical parameters:

Salt Solution Preparation Using the formula of:

The solutions are prepared accordingly to meet the precise testing standards from ISO 9227 or ASTM B117.

Loading Test Samples: Materials that are placed into racks without overlapped materials such that the exposing of the elements is uniform.

Environment Simulation: The chamber temperature is set at (usually between 35°C to 50°C) and the atomizer starts the salt spray process.

Test Duration: From 24 hours up to 1000 hours or more depending on the intended application of the material and the level of corrosion resistance needed.

Evaluation: After the test, the specimens are examined for surface degradation, pitting, or penetration of corrosion using visual inspection and sophisticated analytical methods.
