Introduction

The argon ion polishing /milling is used for the preparation of samples for SEM, EPMA, EBSD, and other applications.

By bombarding the sample with an ion beam, a smooth sample surface can be obtained, providing a large observation area, clean results, and suitability for almost all materials, without causing mechanical damage to the sample.

By removing the damaged layer, high-quality samples can be obtained.

In contrast, samples prepared by mechanical grinding and polishing have rough, uneven surfaces, many scratches and damages, and unclear boundaries.

Representive Results

1. For TEM, SEM, EBSD and LM sample preparation, cross section after Ar ion milling.

2. Mudstone samples before Ar ion polishing.

3. Mudstone samples after Ar ion polishing.

Sample Requirement

1. Sample shape

the sample should be pre-ground and polished, the sample should be flattened, and the upper and lower surfaces of the sample should be parallel.

2. Surface roughness

The polished surface of the sample should be ground with at least 4000 grit sandpaper to ensure it appears smooth and not rough when viewed under a microscope.

3. Sample Size

For block-shaped samples, the diameter should not exceed 30mm, and the thickness less than 20mm. For powder samples, a minimum of 10g is required.
