Ding & Testing Inspection: Precisely Identifying the Roots of Corrosion to Enhance Material Durability
Corrosion product analysis is a technical means that involves detecting and analyzing the composition, structure, and distribution of corrosion products on the surface or inside of materials. It can reveal the type, mechanism, and severity of corrosion, providing a scientific basis for material selection, corrosion prevention design, process optimization, and equipment maintenance, ensuring the reliability and durability of materials and equipment in complex environments.
Service Introduction
Electrochemical testing is a high-precision corrosion assessment method. By measuring electrochemical parameters of materials in corrosive environments, such as corrosion current density, polarization resistance, and charge transfer resistance, it quantitatively analyzes the corrosion rate and corrosion resistance of materials. Electrochemical testing can not only monitor the corrosion process in real-time but also predict the corrosion behavior of materials under specific conditions by simulating actual usage environments.
Testing Methods
Corrosion product analysis employs a variety of advanced detection methods, combining microscopic and chemical analysis to ensure the accuracy and comprehensiveness of the test results. Common testing methods include:
  • Scanning Electron Microscopy (SEM): Used to observe the micro-morphology and surface characteristics of corrosion products, analyzing their distribution.
  • X-ray Diffraction (XRD): Used to analyze the crystal structure of corrosion products, determining their chemical phase composition.
  • Energy Dispersive Spectroscopy (EDS): Used to analyze the chemical composition of corrosion products, providing qualitative and quantitative elemental analysis.
  • Raman Spectroscopy: Used to analyze the molecular structure and chemical bond information of corrosion products, further confirming their composition.
  • Metallographic Analysis: Observing the microstructure of materials with a metallographic microscope to analyze the interaction between corrosion products and the matrix.
  • Chemical Analysis: Analyzing the chemical composition and content of corrosion products through methods such as dissolution, titration, and spectroscopy.
Industry Pain Points
In practical applications, materials and equipment often face complex corrosive environments, such as marine environments, industrial atmospheres, and acidic environments. Corrosion not only reduces the service life of materials but can also lead to structural failure and safety hazards. However, traditional corrosion detection methods often only provide descriptions of surface phenomena and are unable to deeply analyze the roots and mechanisms of corrosion. Therefore, precisely identifying the composition and structure of corrosion products is key to solving corrosion problems.
