Analysis of common methods of hardness measurement

Abstract: hardness is a judgment of the soft and hard of materials, which can be said to belong to mechanical properties. The measurement of hardness is mainly to judge the cracking resistance and deformation resistance of materials. There are many different methods for hardness measurement in related industries

Rockwell hardness measurement method

this method is mainly measured by measuring the depth that can be pressed in. This method can measure quickly and has the advantage of ultra-high efficiency. Only in some special cases, the accuracy of detection is biased. Therefore, this method is most commonly used to detect some batch parts, which can make professional hardness measurement for the finished products of the production line

microhardness measurement

this method can be said to be the measurement method with the least damage to the measured object. This measurement method is often used for the measurement of some small parts

shore hardness test

this type of test method is relatively simple and fast. It is generally used for the detection of large workpieces, such as machine tools or large gears, propellers and other large workpieces

Vickers test method

it can be said that this is one of many test methods with high accuracy for hardness measurement. It can not only measure the hardness of some high hardness materials, but also measure the hardness of some metals or plates. It is only a breakthrough in the research and development and industrialization of the new generation of microelectronic optoelectronic functional materials and intelligent sensing materials. For me, the speed of detection is relatively slow, but the accuracy is very high

Knoop hardness test

this is a method with higher accuracy than Vickers test method. In the same experiment, it is currently regarded by international material giants as the best time to speed up the pace of layout, and the indentation of the measured object will be shallower. It is generally used for the measurement of high hardness metals, ceramic materials and glass materials

there are many methods of hardness measurement, and these methods introduced above are common measurement methods. Its work flow 1 is generally to judge whether the material sample is qualified or reaches the predetermined performance index by clamping the sample material with a fixture, by the force adding device, force value display device and records. According to relevant research, the accuracy of these measurement methods is relatively high. It is proved that because of this, these methods can become the first choice for product hardness measurement in many industries. It is suggested that you can choose the appropriate method according to the actual production needs. Only suitable methods can ensure the accuracy of measurement. After all, the measurement of hardness determines the cracking resistance of the product itself, so the test results are not to be lost. The operation must be carried out strictly to ensure the accuracy of the measurement results

hardness is a judgment of the soft and hard of materials, which can be said to belong to the mechanical properties of ultra energy saving and emission reduction. The measurement of hardness is mainly to judge the cracking resistance and deformation resistance of materials. There are many different methods for hardness measurement in related industries. Next, we will briefly analyze and introduce these methods
