This document specifies the accelerated corrosion test method of metal and alloy soil, including reagents, test devices, soil preparation, samples, test procedures, test results evaluation,and test reports. The soil tests test particularly applies to metals and their alloys in soil corrosion, metallic coatings (anodic and cathodic), conversion coatings. The soil test does not apply to microbiologicalinfluenced corrosionAC and DC corrosion
Soil is a complex, multiphase medium composed of solid, liquid, and gaseous substances. Materials buried in soil are susceptible to corrosion, which is highly concealed due to the inability to directly observe the process. By the time these materials are excavated, some may already exhibit significant rust, with some even corroded through, posing serious threats to the safety of their components or structures. Consequently, it is essential to understand the corrosion resistance of materials in soil before burial.
Current methods for soil corrosion testing primarily include field observation and the use of soilsimulated solutions. Field observation requires a long experimental cycle, while soil-simulated solutions allow for accelerated corrosion and shorter testing durations. However, the latter method immerses test specimens entirely in the solution, which fails to replicate the multiphase composition of real soil. This discrepancy can lead to differences in corrosion morphology and mechanisms compared to actual soil environments, which results in the method might be not suitable for evaluating the corrosion property of metal materials in soils.
To address this, a testing method is needed that preserves the soil corrosion mechanism, accelerates the corrosion process, and effectively simulates the physical and chemical properties of real soil. This project proposes a standardized soil-based test method to accelerate material corrosion processes while conforming to the mechanisms of soil corrosion. This approach enables rapid evaluation of material corrosion resistance in soil, addressing reliability and safety assessment challenges for metal materials in underground engineering.
