Non-destructive analysis Penetrant is generally used for surface discontinuities evident on almost all non-porous materials (the roughness with the excessive flaking) as metals, ceramic, glasses, Plastics, etc.. feature that makes it usable in many fields of application. The LP method was introduced in the industry in the years preceding World War II, the main reason was the need to provide a valid alternative control to magnetizable particle which requires, for application, ferromagnetic material characteristics, especially in the aeronautical field.
- Detection of surface cracks on all metals
- Simple to use
- I need to
- easily interpreted
