Overview: Cerakote in corrosion testing
The corrosion test according to ASTM B117 impressively demonstrates how resistant Cerakote is under aggressive salt spray conditions. The results clearly show why the ceramic coating excels in terms of protective performance: it combines a thin layer with high resistance to corrosion, abrasion, and chemical exposure. For applications with high demands on durability and reliability, the test provides important practical evidence.
This is how the ASTM B117 test is conducted
In the salt spray test, coated components are exposed to a highly corrosive environment under controlled conditions. The goal is to compare the relative corrosion resistance of different surfaces. This method is what makes the ASTM B117 test so meaningful, as it reveals weak points and practically assesses the performance of coatings. Cerakote can demonstrate how stable the surface remains under continuous stress.
What the test results show about Cerakote
The tested Cerakote surfaces last significantly longer compared to many other coatings and show signs of corrosion only very late. According to the published test results, Cerakote clearly outperformed several competing systems and offered exceptionally high resistance to salt spray. This makes the coating particularly interesting for users who need long-term protection with a minimal layer thickness.
Degree of corrosion of Cerakote E-100 Blackout after 4,008 hours, Teflon® Black and Teflon® Metallic Black after 640 hours, and Xylan® after 1,871 hours.
Conclusion: What the test reveals about the protective performance
The ASTM B117 test confirms Cerakote as a powerful solution for demanding environments where corrosion protection is crucial. The coating combines high protective performance with a thin layer thickness, remaining functional, precise, and durable. Those who rely on reliable performance under aggressive conditions will find Cerakote a convincing solution with clear advantages.
