The Advantage of Vickers Hardness Test

The advantage of Vickers hardness test is that its hardness value has nothing to do with the test force. As long as the material is of uniform hardness, the test force can be selected arbitrarily and the hardness value will not change.

This is equivalent to having a uniform scale over a wide range of hardnesses. This is superior to the Rockwell hardness test.

On the other hand, the Vickers hardness tester has a wide test measurement range and can measure almost all metal materials currently used in industry, from very soft materials (a few Vickers hardness units) to very hard materials (3000 Vickers hardness units). ) can be measured.

The Vickers hardness tester is used to measure thin Vickers hardness values. It uses a square pyramid diamond indenter to press into the surface of the sample under the action of the test force. After maintaining it for a specified time, the test force is removed and the indentation on the surface of the sample is measured Diagonal length.

The indentation of the Vickers hardness test is square with clear outline and accurate diagonal measurement. Therefore, the Vickers hardness test is the most accurate hardness tester among the commonly used hardness testing methods.

At the same time, its repeatability is also very good, which is better than that of Brinell Durometer.

In the range of medium and low hardness values, on the same homogeneous material, the Vickers hardness test and Brinell hardness test results will yield approximate hardness values.

The test force of Vickers hardness test can be as small as 10gF, and the indentation is very small, which is especially suitable for testing thin and small materials.

The dimensional hardness tester is small in size, light in weight, does not require a workbench, and can be used in any direction. It is convenient for on-site hardness measurement, has high accuracy, and can also convert multiple hardness values. Therefore, Vickers hardness tester is welcomed by more and more users.
