Material analysis
SAMPLE PREPARATION
Separate
Separation by using the precision separating machine is used to remove small samples from a large sample bodies. The constant cooling combined with the oscillating feed prevents overheating and deformation of the microstructure.
Technical data:
TM Brilliant 250 Wet abrasive cut-off machine
• Sample size: max D = 100
• Feed: oscillating
• Speed: max. 3000rpm
• Cutting discs for various applications
Embed
Here, the samples are positioned / fixed and then pressed with appropriate powder to form a 40mm sample. This makes the samples easier to handle for later processing.
Technical data: Bühler SimpliMet 1000
• Electrohydraulic
•Embedding pressure: 80 to 300 bar
• Embedding temperature: 50 – 180°C
• Press mold: 40mm
Steaming
This allows non-metallic surfaces to be made conductive by vapor deposition with carbon so that analyses can be carried out under a scanning electron microscope. Furthermore, special material analyses can be carried out.
Technical data:
Balzer Union CED 010
• Vacuum: 0.05 mbar
• Material for steaming: carbon yarn
