What is a Mixed Gas Corrosion Test?
A mixed gas corrosion test evaluates material resistance in complex gas environments. By simulating real-world industrial conditions—including fluctuating gas concentrations (e.g., O₂, CO₂, H₂S, SO₂)—it predicts how metals, plastics, coatings, and composites degrade. This testing is critical for lifespan prediction, material selection, and quality assurance in automotive, aerospace, and manufacturing sectors.
Key Functions & Applications
- Realistic Simulation
Replicates corrosive industrial atmospheres with mixed gases (humidity, O₂, H₂S) to deliver accurate performance data. - Multi-Material Testing
Assesses metals, polymers, rubbers, coatings, and composites under adjustable temperature, humidity, and gas variables. - Coating & Composite Validation
Measures protective layer efficacy (adhesion, corrosion resistance) and composite material stability. - Lifespan Prediction
Accelerates corrosion to forecast product durability and maintenance needs.
How to Perform a Mixed Gas Corrosion Test
- Select Gases
Choose relevant corrosive gases (oxidizing, reducing, inert) based on the target environment. - Prepare Samples
Clean and mount materials (metal plates, coated surfaces) securely in the test chamber. - Set Parameters
Configure temperature (20°C–60°C+), humidity (40–100% RH), pressure, and gas concentrations. - Run & Monitor
Initiate tests (cyclic, constant, or accelerated) and track corrosion progression via sensors. - Analyze Results
Evaluate corrosion rates, surface changes, and material degradation post-test.
