The Vickers hardness test method, also referred to as a micro hardness test method, is mostly used for small parts, thin sections, or case depth work.
An optical measurement system is used in the Vickers method. The Micro hardness test protocol, ASTM E-384, describes a range of low stresses that are measured and converted to a hardness value using a diamond indenter. It’s great for evaluating a variety of materials, but test samples must be properly polished so that the size of the impressions can be measured. In the Vickers scale, testing is done with a square base pyramid shaped diamond. Loads are typically modest, ranging from 10gm to 1kgf, while “Macro” Vickers loads can weigh up to 30 kg.
The Micro hardness methods are used to test on metals, ceramics, and composites – almost any type of material.
Micro Vickers Hardness Tester Description:
- A new generation of Vickers hardness tester integrated design of hardness tester and computer;
- Testing parameters can be selected on the panel computer. With touching screen, it operates quickly and conveniently and displays clearly and intuitively.
- With CCD image acquisition system, it can show dynamic indentation image, lock the image and automatically calculate the Vickers hardness value.
- High measuring accuracy and stable performance, avoiding human errors
- With Windows 7 operating system, it has all functions of computer. Also can be connected to the monitor, printer and other output devices.
- With three measuring objectives, automatic recognition and shifting between the objective and the indenter. The lifting screw adopts the worm and gear structure for smooth transmission.
- Automatically save the measuring data, generate the hardness-depth curve and save as WORD document.
- With built-in CCD image automatic measuring system, the indentation displays clearly and intuitively and the hardness value can be automatically got.
- Digital X-Y Anvil makes the measurement more accurate, and it can be equipped with X-Y automatic test table (optional) to realize the automation of Vickers hardness testing.
