What is Accelerated Corrosion Testing?

Performed in a material testing laboratory,  accelerated corrosion testing helps predict how materials or coatings will perform in harsh environments. By exposing samples to controlled conditions like salt spray, humidity, and temperature cycles, it is possible to simulate years of environmental wear in a few weeks.

These types of tests are essential for identifying corrosion resistance in a given material in order to improve its formulation and ensure compliance with industry standards.

Accelerated corrosion testing is widely used across industries to:

  • Compare the performance of different coatings or treatments
  • Validate compliance with international standards and OEM specifications
  • Support research and development of new materials

Which Methods are Used to Perform an ACT?

There are two main types of methods used to perform an Accelerated Corrosion Test (ACT). At Micom, we offer both static and cyclic testing to meet a wide range of industry standards and client-specific requirements. Using advanced salt spray equipment (Q-FOG) and climatic testing chambers, we can simulate diverse environmental stresses to provide a comprehensive evaluation of your materials and coatings.

Static Corrosion Testing

This method exposes samples to constant environmental conditions, such as a continuous salt spray or humidity. A common example is the ASTM B117 Salt Spray Test, which evaluates a coating’s resistance to salt-induced corrosion over time.

Cyclic Corrosion Testing (CCT)

Cyclic corrosion tests alternate between different environmental conditions, such as salt spray, drying, humidity, and temperature fluctuations, to better mimic real-world exposure. This method is often used in the automotive industry and includes standards like SAE J2334, VDA 621-415, and Ford CETP 00.00-L-467.

Post-Test Methods Related to Accelerated Corrosion Testing

After testing, our experts conduct thorough evaluations to quantify corrosion damage and validate coating performance. These assessments support R&D, quality assurance, and regulatory compliance. Depending on your material and test type, we can assess:

  • Coating blistering, cracking, and delamination
  • Rust creep and scribe failure (ASTM D1654)
  • Surface degradation and discoloration
  • Mass loss and thickness change
  • Adhesion loss after exposure

These analyses support failure investigations, product validation, and compliance documentation.
