The Salt Spray Test Laboratory

An overview of the test chambers and technical expertise dedicated to evaluating the corrosion resistance of complex materials and components.

Corrosion Testing Methodology and Phases

The laboratory testing process replicates accelerated aging scenarios to promptly identify any structural deficiencies.

  • Accelerated Simulation: A neutral salt spray consisting of water and sodium chloride (NaCl) is used to reproduce accelerated corrosion conditions over a relatively short period of time.
  • Chamber Exposure: Samples are exposed to the solution inside a specially designed chamber, maintaining constant conditions for a defined period.
  • Test Duration: Depending on specific requirements and the material, tests can last up to thousands of hours, simulating real-world exposure to atmospheric agents over several years.
  • Analysis of Results: At the end of the exposure, technicians examine the samples to identify corrosion effects, deformation, or surface damage.
