For non -destructive analysis of the hardness of the structure, devices are used, called a solider. There are certain areas of industrial production, where the use of these devices is necessary and important to buy a solidomer for the enterprise:
– in the production of raw materials and blanks;
– in the implementation of quality control of finished products;
– when creating new production technologies in laboratories and research institutes;
– In the manufacture of new parts and designs.
What are solidomers
To measure the hardness of some parts and blanks, special solidomers are required, therefore, they are divided by the method of use by:
– portable;
– stationary.
Portable solidomers are used to measure the strength of the parts and workpieces of large size. Also in demand in the measurement of hardness of the workpieces is sclerometers. At the beginning of the last century, the method of scratch or sclerometry was the most recognized and was considered a reference. In the middle of the last century, sclerometers were almost completely replaced by solidometers using the methods of Brinnel, Rockwell, Vickers and others.
Nevertheless, sclerometers are used today. This name is used to determine any device that measures strength, hardness, plasticity, wear resistance, mechanical features by scratching. As was said, the hardness of the material is determined by various scales. Their use is determined by the technical documentation and the characteristics of the test material.
How a solidter works
For all scales of measurement, it is unchanged: the test surface is subjected to mechanical effects. By reaction to the exposure of the surface, they judge the hardness, strength or plasticity of a particular material. A portable solidomer to determine strength can use an ultrasound, mechanical or dynamic method. The mechanical method, as noted, is that the surface of the product is subjected to mechanical stress, a dynamic or shock method is that the state of the surface is measured after shock exposure. The ultrasound measurement is that the sensor is introduced into the test surface. The surface strength is judged by a change in fluctuations and frequency.
On the site of the manufacturer, you can buy measuring devices to determine hardness in a wide range. Solidomers are used to determine the strength of such surfaces as plastic, concrete, metals, etc.
