Micro Vickers Hardness Tester: Precision Hardness Testing for Microstructures

The Micro Vickers Hardness Tester is a highly accurate and reliable instrument designed for measuring the hardness of small, thin, or delicate materials. With advanced technology and precision engineering, this testing equipment is widely used in industries like metallurgy, automotive, aerospace, and research laboratories. It is especially beneficial for evaluating coatings, thin films, and microstructures that require minute indentation loads.

What is a Micro Vickers Hardness Tester?

A Micro Vickers Hardness Tester is a specialized hardness testing machine that uses a diamond pyramid-shaped indenter to measure the hardness of a material. This method, known as the Vickers Hardness Test (HV), is based on applying a specific load to the sample and calculating the hardness value from the size of the indentation left on the material’s surface.

This testing method is particularly suitable for small parts and coatings where high precision is necessary. The results obtained are highly accurate and repeatable, making it a preferred choice for material scientists and quality control engineers.

Working Principle of Micro Vickers Hardness Tester

The working principle of a Micro Vickers Hardness Tester follows these steps:

1. A diamond indenter with a square-based pyramid shape is pressed into the material’s surface under a controlled load (ranging from a few grams to 1 kgf).
2. The load is maintained for a specified dwell time to ensure proper indentation.
3. After removing the load, the diagonal lengths of the indentation are measured using a high-resolution microscope.
4. The Vickers Hardness Number (VHN) is calculated using the formula:

VHN = (1.854 × Load) / (Diagonal Length)^2

5. The final hardness value helps determine the material’s resistance to deformation, wear, and fatigue.

Key Features of Micro Vickers Hardness Tester
