ISO 18070 Crevice Corrosion Evaluation
The ISO 18070 standard is a critical tool in the assessment of crevice corrosion susceptibility, particularly for materials used in harsh environments. This method evaluates how susceptible metallic components are to localized pitting and corrosion at geometrically constrained areas such as crevices, which can lead to premature failure in various industrial applications.
Crevice corrosion typically occurs where two dissimilar metals meet or when a liquid environment is present within confined spaces, promoting an electrochemical cell. This form of corrosion is particularly challenging because it often proceeds undetected until significant damage has occurred. The ISO 18070 method addresses this challenge by providing a standardized approach to evaluate crevice susceptibility.
The test involves the immersion of specimens in a specific chloride-containing solution under controlled conditions, which simulate real-world environments where crevice corrosion can occur. The process is designed to be repeatable and reproducible across different laboratories worldwide, ensuring that results are consistent and comparable.
Specimen preparation for this method is critical; it involves creating precisely defined crevices in the material surface using a mechanical or chemical means. This ensures that the test conditions accurately reflect real-world scenarios where crevice corrosion can occur. The specimens are then immersed in a solution of 3% sodium chloride (NaCl) at 60°C, with agitation to simulate fluid flow within the crevice.
Testing duration varies depending on the material and expected susceptibility, but it typically ranges from a few days up to two weeks. During this time, any corrosion that develops is carefully monitored using visual inspection or non-destructive testing techniques. The presence of pitting or other signs of localized corrosion in the crevice indicates a higher susceptibility to crevice corrosion.
The ISO 18070 method is widely recognized for its precision and reliability, making it an essential tool for industries such as aerospace, automotive, and marine, where materials must withstand harsh environmental conditions. By identifying susceptible materials early in the design process, companies can make informed decisions about material selection and corrosion protection strategies.
Understanding crevice corrosion susceptibility is crucial for ensuring product longevity and safety. This method helps quality managers and compliance officers ensure that their products meet stringent regulatory standards and performance expectations. For R&D engineers and procurement professionals, ISO 18070 provides a clear path to selecting materials that are robust enough to withstand the rigors of their intended applications.
The standard is also valuable for forensic analysis, where identifying the cause of corrosion failure can be critical in product development and quality assurance. By using this method, manufacturers can avoid costly recalls and improve overall product reliability.
