Sample preparation
Samples provided to Mintek for failure investigations and quality evaluations are prepared by sectioning, mounting and then grinding and polishing. The MTC has several cut-off machines for sectioning samples depending on size:
- Horizontal Band Saw - for sectioning large samples.
- PowerMet 300 Abrasive Cutter - for sectioning manageable samples.
- Manual Cutter - for sectioning manageable samples.
- Discotom-60 Abrasive Cutter - for sectioning manageable samples.
- Exotom Abrasive Cutter - for sectioning manageable samples.
- FSG-2A20 Surface Grinder - for smooth and flat surface finish.
- Secotom 10 - for precision cutting of small samples.
Samples are hot or cold mounted depending on the size and desired analysis and are then ground and polished to the desired finish. The MTC also has equipment for electro-polishing samples and has experience with a significant number of etchants.
