Microscopic testing includes methods that use microscopic instruments to search for characteristics below the surface of a material, or those too small to be detected by the human eye alone. These types of evaluations are generally performed using a high-powered optical microscopic equipment. These methods apply when examining the subsurface of a material or a small section of a larger sample.
Some of the methods that we use include:
- General Microstructure
- Banding
- Casting evaluation
- Case Depth (Carburization/Depth of decarburization)
- Coating thickness
- Failure analysis
- Ferrite content
- Grain Flow
- Grain size
- Inclusion content and severity
- Intergranular corrosion
- Intermetallic phase determination
- Microstructure evaluation
- Nitriding
- Passivation
- Pitting and crevice corrosion
- Porosity
- Replication metallography
- Volume fraction
- Weld Evaluation
