Ding & Testing Inspection: Rapidly Assessing Material Durability to Support Efficient Material Screening and Optimization
Accelerated corrosion testing is a detection technology that simulates and intensifies actual corrosive environmental conditions to accelerate the corrosion process of materials. It can simulate the corrosion behavior of materials over long-term use within a short period, providing a scientific basis for material durability assessment, corrosion prevention design, process optimization, and quality control, significantly reducing the research and development cycle and costs.
Service Introduction
Accelerated corrosion testing is an efficient corrosion assessment method. By artificially controlling and intensifying corrosive environments (such as increasing temperature, raising the concentration of corrosive media, and introducing acidic or salt spray conditions), it accelerates the corrosion process of materials. This testing method can simulate the corrosion conditions that materials may face in actual use within a short period, quickly assessing the corrosion resistance of materials and providing important references for material selection and corrosion prevention design.
Testing Methods
Accelerated corrosion testing employs various standardized testing methods, combining laboratory simulation and data analysis to ensure the accuracy and reliability of the test results. Common accelerated corrosion testing methods include:
-
Salt Spray Testing (NSS, AASS, CASS): By spraying saline solutions, it simulates corrosive conditions in marine or industrial environments.
-
Cyclic Salt Spray Testing: Alternating samples between salt spray, dry, and humid environments to simulate the corrosion process in complex environments.
-
Acidic Salt Spray Testing: Adding acidic substances (such as acetic acid or sulfuric acid) to the salt spray to simulate corrosive behavior in acidic environments.
-
High-Temperature and High-Humidity Testing: Accelerating the corrosion process of materials under high-temperature and high-humidity conditions to simulate tropical or humid environments.
-
Electrochemical Accelerated Testing: Using electrochemical methods (such as polarization potential, electrochemical impedance spectroscopy) to accelerate the corrosion process and monitor the corrosion rate in real-time.
Industry Pain Points
In practical applications, materials and equipment often face complex corrosive environments, such as marine environments, industrial atmospheres, acid rain, and high humidity. Corrosion not only reduces the service life of materials but can also lead to structural failure and safety hazards. Traditional natural exposure testing is time-consuming and inefficient, failing to meet the needs of rapid research and development and quality control. Therefore, accelerated corrosion testing, as an efficient and reliable detection method, can significantly shorten the research and development cycle and quickly assess material durability.
