What is microindentation hardness testing?
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.
Our Surface Mechanical Tester SMT-5000 combines piezo actuation and capacitive sensing technologies. The micro indentation head – IST brings the highest precision measurements, from nano to micron ranges. In addition, the SMT-5000 merges the ability to measure mechanical properties. Such as, hardness, modulus, scratch adhesion, film thickness, surface roughness, 3D imaging, and many others.
Besides the IST module, the SMT-5000 incorporates environmental modules (temperature, humidity, corrosion). All these capabilities of the SMT-5000 provide the use of 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 also uses 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?
Why IIT is Different
IIT brings additional information about the material. Such as the elastic modulus, that the conventional hardness could not measure. Additionally, the direct calculations of the area used for Hardness in IIT eliminate the possible errors introduced by users. It instead measures the imprint optically rather than traditional hardness tests. Finally, the use of much lower forces in IIT allows 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 applying 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 to the material, the test’s unloading portion represents the material’s elastic response. A fitting of the unloading curve accompanied by using different models yields the value of the elastic modulus.
