Mechanical - Microindenter

Micro-hardness testing permits measuring the hardness of a material on a microscopic scale. The Qness Q60 A+ microindenter is a fully automated system with quick and precise positioning relative to the sample. The machine is equipped with three different magnification lenses (10X, 40X, and 65X) and three indenters (Vickers, Knoop and Brinell), which facilitate hardness measurements across a broad range of materials. Samples with varying heights and tilts can be indented at the same time with the Qness CAS sample holders. Additionally, the indenter can be adapted to the respective contour of the test sample such that different material regions (i.e. e.g. layers) can be tested precisely. Additionally, users can obtain the hardness distribution across a segment or whole plane of the test sample using the 2D/3D mapping tool.

 


Highlights

  • Fully automatic image evaluation for measurements
  • Moveable XY platform for automated batch measurements and hardness measurement mapping
  • Maximum sample size: 150 mm (width), 150 mm (length), 145 mm (height)
  • Force ranges from 0.25 g to 62.5 kg
  • Indentation tips: Vickers diamond, Knoop diamond, Brinell 1 mm ball

 


Sample Requirements 

In order to obtain a regular indentation shape, the sample surface should be perpendicular to the indentation tip. In order to obtain reliable measurements, the sample surface should be smooth (preferably polished), to ensure that the edges of the indents can be visually identified. 

Samples can either be mounted or unmounted. 
For mounted samples, mounts with diameters of 25 mm, 50 mm, 1.25 inches, or 1.5 inches are preferred. Mounts should not have a rounded or chamfered edge.   
For samples which are not mounted, sample surface should be perpendicular to the indentation tip.
