Nano-impact testing is particularly suitable for high strain rate contact testing. The strain rates of nano-impact testing are typically 100-1000 s-1, much greater than the nano-indentation strain rates of 0.0001 – 0.01 s-1.
Nano-impact testing was originally designed to assess the toughness and fatigue fracture resistance of thin films and coatings. Nano-impact testing is also able to mimic highly loaded repetitive contact situations.
In operation, components in a wide variety of applications undergo vibrational wear. Fretting tests are regularly run on the macro-scale in order to examine material behavior under these conditions.
The nano-fretting module allows investigation of fretting and reciprocating wear at the micro/nano scale filling the previous metrology gap.
Mechanical properties of materials often vary considerably when in their normal fluid environment compared to the usual laboratory dry testing conditions. Probing the mechanical properties of biological samples in fluid media should prove a closer mimic of in vivo conditions than conventional dry nanoindentation testing.
The liquid cell allows nanoindentation, nano-scratch & wear testing of samples fully immersed in liquid. A friction transducer extension also allows immersed sample friction measurements.
The properties of many materials can vary significantly with changes to humidity. This can be especially true of polymeric or biological samples. Obtaining meaningful test results for prediction of true-life performance is better achieved by closely simulating service conditions. The rapid change Humidity Cell module can assist considerably in achieving this.
