GB/T 17455-1998
AbolishedNon-destructive testing--Metallographic replica techniques of surface examination
无损检测 表面检查的金相复制件技术
Application Summary AI generated
This standard specifies the procedures and requirements for using metallographic replica techniques to examine surface microstructures and defects without damaging the component. It is applied in industries such as power generation, aerospace, and petrochemicals for in-field inspection of high-temperature components like turbine blades, boiler tubes, and pressure vessels. The technique enables assessment of material degradation, creep damage, or cracking by transferring a surface impression to a replica film for laboratory analysis.
