On-site materialographic
preparation and examination
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.
The usual preparation steps such as grinding, polishing and etching are
performed on the part to be examined in a limited area where no damage can
be done, whereupon the surface can be analysed.
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.
Struers manufactures a complete range of portable equipment for non-
destructive preparation, from basic grinding through mechanical and electrolytic pol-
ishing to electrolytic etching. The range also includes a portable microscope for on-
site use and methods for producing replicas of the prepared surface.
Non-destructive
preparation
Using replica methods makes it possible
to perform the microscopic examination
in the laboratory - under perfect working
conditions.
The entire Struers non-destructive prep-
aration range has been designed for field
work. The equipment is thus as compact
and as light as possible. It is easy to
transport and can be used literally under
any conditions.
