High Temperature Vickers Hardness

Testing System HTV-PHS 30

High temperature hardness is undoubtedly unique and unique in many material performance tests. In the field of dynamic mechanics, materials are heated up instantaneously under high strain conditions, resulting in instantaneous changes in strength and hardness. Therefore, the relationship between temperature and hardness is the key index to study material damage and failure. High temperature hardness test system is a very necessary equipment for dynamic mechanics research 。 Because hardness test is a destructive test, the hardness of materials will change at any time under different temperatures, and a single test method can not get the exact hardness value of the same sample under different conditions, so we need to measure the hardness of materials under different conditions in different ways, which is the existence power of our high temperature hardness. High temperature hardness test is to measure the hardness of materials at a higher temperature. High temperature hardness is very necessary in many cases, such as tool steel materials, wear-resistant coating, such as valve seat and application mold, which are all used at high temperature. High temperature hardness can identify different properties of various materials at high temperature, which has great practicability. It can not be used to evaluate the high temperature performance because the change of indoor temperature is not related to the change of hardness. However, the hardness of materials changes greatly when the temperature changes significantly, such as tempering, wear, corrosion and thermal erosion. Therefore, the problems of pressure and high temperature creep fracture performance, aging, sliding wear, softening, creep deformation and other problems are to be solved by studying the high temperature hardness of materials. In general, materials become soft under high temperature, which may lead to wear. This kind of adhesive wear and material damage between metal surfaces are common causes of failure of parts or equipment in industry, which can not be studied carefully. The instrument can measure the Vickers hardness from normal temperature to high temperature, which is most suitable for testing the high temperature hardness of new materials such as heat-resistant metal materials and ceramic products. High temperature furnace: the high temperature furnace is a rotating device which is connected with the shaft and can observe the test sample. It is a sealed heating chamber with a sample heating device and a moving device of the sample heating part. Heating environment: first, heat the furnace to the required temperature, and then measure the hardness. Test method: the shaft part of high temperature furnace keeps the furnace sealed and makes the furnace rise and fall freely. The test force can be applied from the furnace to the sample inside the furnace. Moreover, the control of the test force and the test force applied from outside the furnace depends on the Vickers hardness tester. Conversion of test force loading and unloading and specimen indentation test: align the indenter installed on the rotating plate on the upper part of the high temperature furnace with the specimen position, load or unload, and then rotate the observation window to the specimen position, and use CCD to measure the indentation diagonal and read the Vickers hardness value. 1. Indentation manufacturing system: This is the core part of a complete system of hardness tester, which mainly involves the mechanical property test. No matter the loading time and the holding time, they need to be precisely controlled. The instrument adopts the loading principle of closed-loop servo sensor, uses the C-shaped structure to enhance the rigidity of the instrument, and uses the limited technical parameters to analyze the influence of temperature and test force. The instrument adopts force value timely supplement mechanism. First, there is no violent impact between lever and weight during loading and unloading, and it has overload protection function. The conversion between force values can be realized automatically, which is very convenient, and the loading speed can be adjusted
