SMT-5000 Microindentation Tester


Instrumented Micro indenter, with scratch tester and in-line 3D profilometer to measure the micro hardness, modulus, roughness, adhesion, and film thickness of surfaces with highest accuracy and repeatability on one tester.

3D Microhardness Tester Overview

Main Features

  • Widest Range mN to 40N on one head.
  • Both indentation and scratch with same head.
  • Piezo and capacitive based for high precision.
  • Patented image correlation between data and 3D images.
  • In-line 3D Profiler to quantify cracks, pileups, defects, roughness, and position.

Microindentation hardness testing (or microhardness testing) is a method to measure the hardness, modulus and several other properties of a material on a microscopic scale.

Combining piezo actuation and capacitive sensing technologies, the microindentation head – IST brings the highest precision measurements from nano to micron ranges with same head. The platform Surface Mechanical Tester SMT-5000  merges the ability to measure mechanical properties, such as hardness, modulus, scratch adhesion, film thickness, surface roughness, 3D profilometer and many others.

Besides the IST module, the SMT-5000 incorporates environmental modules (temperature, humidity, corrosion). All these capacities allows to use microindentation  for quality control or cater to demanding engineers and researchers in many fields.

    What is a Microindentation Tester?

    The Rtec Instrument microindentation tester (or microhardness tester) measures hardness, elastic modulus, and many others at a microscopic scale. Read more below on how the SMT-5000 answers common microindentation testing questions.


    What is Instrumented Indentation testing?

    Instrumented Indentation Testing (IIT) involves pressing an indenter of known geometry into a surface while controlling and measuring the force and displacement. The resulting load-displacement curves are used to calculate hardness and elastic modulus among other things.

    How is hardness measured in indentation?

    Hardness is defined as a contact pressure (Force by contact area).

    Traditional hardness tests use the maximum force applied on the tip and the visual measurement of the size of the imprint left into the material (after removal of the force) to calculate Hardness values.

    IIT uses also the maximum force applied on the tip but calculates the true cross-sectional area of contact between the tip and the material at the point of maximum force

    What is the difference between IIT and traditional hardness tests?

    IIT comes for the evolution of the traditional hardness tests. IIT brings additional information about the material such as the elastic modulus, that the traditional hardness could not measure.

    Also, the direct calculations of the area used for Hardness in IIT eliminates the possible errors introduced by users measuring the imprint optically in traditional hardness tests. Finally, the use of much lower forces in IIT allow for the investigation of much smaller volumes of materials. This opens the ability to measure coatings independently from their substrate.

    How is modulus measured using IIT?

    Elastic modulus is the ability of a material to “bounce back” after the application of a stress. By its control and recording of force and displacement, IIT can provide the elastic modulus of the material tested by studying the unloading portion of the test. After the maximum force is applied onto the material, the unloading portion of the test represents the elastic response of the material. A fitting of the unloading curve accompanied with the use of different models, yields the value of the elastic modulus.
