Analysis of metal and plastic materials

These analyses concretely demonstrate the material’s quality and are indispensable:

For the quality control of the materials procured;
For checking that they match the manufacturer’s certification;
In the automotive sector, for qualifying and checking conformity of the welding process.

They allow to shorten material non-conformity, return and replacement management times. They guarantee the elimination of downtime caused by bad quality/wrong supply of procured materials. In the case of metallic materials, we offer SEM, EDS (including elemental mapping and line-scans), macrographic and micrographic analyses, hardness tests. In the case of plastic materials: SEM, EDS (including elemental mapping and line-scans), DSC, IR, tensile strength tests.

Hardness Test

Hardness testing is a method used to determine a material's resistance to penetration or indentation by a standardized indenter.

The principle of hardness testing involves creating an indentation on the material's surface using an indenter to which a force is applied.

This determines the resistance offered by one material to being penetrated by another.

By making a micro-indentation on the sample surface over a relatively brief period, hardness testing is often preferred for gaining reasonably reliable indications regarding the tensile strength of materials.

There are various scales used to measure material hardness:

* **Brinell**
* **Vickers**
* **Rockwell**
* **Barcol** or **Shore-D** (for polymeric materials)

Donegani Anticorrosione possesses a wide range of durometers capable of covering the various hardness scales, thanks to the latest generation of portable and manual instruments.

The laboratory is also equipped with an automatic durometer for performing Vickers micro-hardness tests.
tensile test

Available for both metallic and plastic materials, it allows for the determination of the material's mechanical characteristics.
