Conventional materialographic preparation entails cutting a sample from a material. This method is not always appropriate as it destroys the component which is being examined.
Many applications require the ability to perform a materialographic preparation and examination without ensuing damage to the subject. The non-destructive method is used in these cases.

Struers manufactures a complete range of portable equipment for non-destructive preparation, from basic grinding through mechanical and electrolytic polishing to electrolytic etching.

On-site preparation is particularly suitable for quality checks in power stations, oil platforms, bridges, aircraft etc. The non-destructive preparation method enables the necessary inspection to be carried out on site.
