1 Introduction

The semi-automatic micro Vickers hardness tester integrates the latest professional technologies such as optical imaging, mechanical displacement, electronic control, digital imaging, image analysis, computer processing, etc. The control of the Vickers hardness tester and the automatic stage is realized through the host computer. , And digitally image the hardness indentation on the computer screen, and then accurately measure the microhardness, hardened layer depth, and thickness of metal and some non-metallic materials, various coatings, and coatings through automatic and manual readings. , Two-point spacing, etc. It can also photograph the topography of the metal surface and perform fixed-magnification printing. This system breaks through the traditional hardness test method and realizes semi-automatic, high-precision, high-repeatability hardness test. It is an important equipment for material analysis.

materials introduce
Pressure control When the test force of the hardness tester is converted, the system senses the change of the test force and displays it in the system in real time.
Turret control The software controls the hardness tester to switch between the objective lens and the indenter without manual control of the hardness tester.
Load control The software controls the hardness tester to load, without manual control of the hardness tester.
Measurement control The software controls the hardness tester turret, loads and directly reads the Vickers hardness value
Light source brightness control Set the brightness of the light source
Image Acquisition Real-time display of hardness images, images can be stored, printed, and printed at fixed times.
Manual/automatic measurement Manual: pull diagonal measurement, two-point card line measurement, four-point measurement, automatic: automatically find the four vertices of the indentation, fast speed, accurate data. Continuously hit and measure, hit and measure immediately, and suppress by designated coordinates.
Hardness conversion According to Chinese standards, automatic conversion of Brinell-Rockwell-Vickers-Knoop hardness values, real-time display, and conversion to various international standards
Graphic report

Automatically record the measurement data, automatically generate the hardness-depth curve, save or print the hardness-depth curve and all indentation measurement values; save or print the indentation image and the current indentation hardness value;

The inspection report can be customized according to user requirements; through the data processing software, the hardened layer depth value formed after continuous measurement of the sample can be displayed in the form of a table; various measurement data, D1, D2, hardness value table, hardened layer depth, Maximum value, average value, minimum value, display and output each indentation picture. Data such as hardness value, hardness table, hardened layer depth map and picture insertion can be flexibly edited and printed in WORD or EXCEL to print out a test report containing mathematical statistics and hardened layer depth curve and saved in WORD format or EXCEL, and the observed samples can also be printed The topography map is saved and directly reflects the microstructure of the indentation and background,
