Corrosion
Testing
Corrosion testing proves how your components and coatings hold up against rust, salt, and harsh environments - long before they reach the field. Magnus Sourcing uses accelerated corrosion testing to validate the durability of platings, paints, and surface treatments, giving USA and global clients confidence in long-term performance.
What is Corrosion Testing?
Corrosion testing exposes a component to controlled, accelerated environments - such as salt spray, humidity, and corrosive chemicals - to predict how it will resist rust and degradation over its real-world service life. It is the definitive way to verify the quality and thickness of protective coatings like zinc plating, powder coating, anodizing, and phosphating.
For our clients, this means surface treatments are validated to international standards before shipment - ensuring parts survive marine, automotive, and industrial conditions without premature failure.
Why It Matters
- Proven coating durability before shipment
- Validates plating & paint quality
- Predicts real-world service life
- Meets ASTM B117 & ISO standards
- Prevents field failures & warranty claims
- Traceable, certified test reports
What We
Test
Salt Spray (Fog) Test
- Continuous salt mist exposure (ASTM B117) to measure how long a coating resists red rust and white corrosion.
Humidity & Cyclic Testing
- Controlled humidity and alternating wet/dry cycles that simulate years of real-world weathering in days.
Coating Integrity
- Adhesion, thickness, and breakdown assessment on plated, painted, anodized, and phosphated surfaces.
