Overview

HT-VCK-MD microhardness tester, based on the principle that positive quadrangular pyramid diamond indenter presses the surface of the sample to produce indentation. By measuring the diagonal length of the indentation to achieve the measurement of the hardness of the material can be for small specimens, thin specimens, surface coating, heat treatment of the work piece surface Vickers hardness test With stable performance, strong structure, high reliability, simple operation, adopt high magnification optical measurement system, adjust the cold light source, photoelectric sensing technology and computer-aided means it has a powerful function 11 is widely used in the fields of metal processing, electronics industry, mold parts, watch manufacturing, engineering quality inspection and so on. 11 is an ideal hardness tester for material research and testing.

Working Principle

Micro-Vickers (or Knoop) hardness 1st principle is that put the provisions of the positive pyramid diamond indenter into the sample surface (with fixed experimental force) and maintain a certain length (holding), and then unloading. Finally, there is a positive quadrangular pyramid or ken up indentation with a square surface on the surface of the specimen. Then we can attain the area of indentation via measuring the length of the diagonal by a micrometer eyepiece. Then the corresponding Vickers (or Knoop) hardness values are obtained.  HT-VCK-MD microhardness tester, based on the principle that positive quadrangular pyramid diamond indenter presses the surface of the sample to produce indentation.
