Cyclic Corrosion Testing

Laboratory Testing (LTI) performs advanced cyclic corrosion testing to evaluate coating durability, plating performance, and corrosion resistance under controlled environmental cycling conditions.

• Multi-stage cyclic corrosion exposure testing
• Programmable environmental chamber cycles
• Salt spray, humidity, and dry cycle exposure
• Testing per automotive and OEM specifications
• Evaluation of plated, coated, and painted components
• Corrosion rating per specification requirements

Typical Applications

Industries rely on cyclic corrosion testing to evaluate coating performance and corrosion protection under simulated real-world service conditions.

• Automotive components and assemblies
• Fasteners and plated hardware
• Structural steel and coated components
• Aerospace and defense coatings
• Industrial equipment exposed to corrosive environments

Test Parameters

Cyclic corrosion testing is conducted using programmable environmental chambers designed to simulate multiple environmental conditions within a single test cycle.

• Alternating salt spray, humidity, and drying cycles
• Controlled chamber temperature and humidity conditions
• Exposure cycles ranging from several days to multiple weeks
• Evaluation per OEM and industry corrosion rating standards
• Custom protocols per specification requirements

Traditional salt spray testing exposes materials to a constant saline environment. Cyclic corrosion testing introduces repeated environmental changes including wetting, drying, and humidity exposure that more accurately simulate real-world corrosion mechanisms.

These protocols are commonly required by automotive manufacturers to validate corrosion protection systems and ensure long-term component durability.
