Nanomechanical Wear-Box Test

Nanomechanical Wear-Box Test
Wear Image captured of 2 different wear volumes measured using distinct wear profile methods in LaO coating

Nanomechanical wear testing (nano-wear box) is a nanomechanical testing mode – similar to nano-indent and nano-scratch analysis – used to evaluate wear resistance and other mechanical properties at sub-micron scales.

Strengths
  • Highly flexible and customizable wearing modes
  • Optimized to test durability for films down to 1 nm in thickness
  • Efficient data collection
  • Minimal sample preparation
Limitations
  • Destructive
  • Not well suited to very-soft sample materials
  • Ultra-thin layers (less than 100 nm thick) require method development to set optimum force and tip conditions

How Nano-wear Works

Nanomechanical wear-box testing evaluates numerous mechanical response properties and resistance to both linear and nonlinear processes associated with deformation and sample damage under sustained, iterated, or dynamic forces.

For nanomechanical wear testing, the sample surface is subjected to a raster-scanned user specified force applied with an indenter tip. The scan can involve one, or many passes over the same area, with customizable displacement, static- and dynamic load behavior, and raster properties.

After the wear test has executed, optical profilometry using Laser Scanning Confocal Microscopy (LSCM) is performed to image and characterize the damage pattern throughout the analyzed volume (the “wear box”).

The resulting images and measurements, along with metrics of the applied force on the probe, its displacement, and ambient environmental conditions, are all used to analyze the mechanical wear resistance of the sample.
