Abstract

The invention discloses a full-automatic microhardness device capable of measuring a force-displacement curve. The device comprises an XY-direction motion control platform, a Z-direction motion control platform, a control system and a fixed force sensor with a hardness head, wherein the Z-direction motion control platform is arranged on the XY-direction motion control platform, the fixed force sensor with the hardness head is arranged above the Z-direction motion control platform, and the control system is connected with the force sensor with the hardness head, the XY-direction motion controlplatform and the Z-direction motion control platform. The force-displacement curve is automatically generated in a process of measuring microhardness, and an F-D curve is analyzed so that various material performance parameters can be conveniently obtained, and characterization of the material is realized.

Description

technical field [0001] The invention relates to the technical field of automatic measurement, in particular to an automatic microhardness device capable of measuring force-displacement curves. Background technique [0002] The main function of the microhardness measurement system is to measure the microhardness parameters of the workpiece, which is widely used in machinery manufacturing, chemical industry, metallurgy, semiconductor technology and other fields. [0003] The Vickers microhardness tester is a widely used hardness tester at present, and the micro Vickers hardness is a kind of Vickers hardness. According to the size of the test force, Vickers hardness can be divided into Vickers hardness test, small load Vickers hardness test, and micro Vickers hardness test. The test force range of micro Vickers hardness is between 0.09807≤F<1.961. Because of its small test force, it has many functions and properties that other hardness test methods do not have. This detec...
