Knife  Engineering coatings are applied to materials to enhance their performance and increase their durability. As they are often thin, many of the techniques that are employed need to have a high spatial resolution (e.g. nanomechanical testing) so that the properties of the coatings can be determined. The need for high resolution techniques is emphasied by the fact that many engineering coatings now have a structure on the nano-scale.

Other techniques that are being investigated are:

  • laser surface acoustic spectrometry
  • impact excitation
  • bend testing
  • scratch testing

It has been found that when these techniques are used in combination, it often proves more powerful, giving more accuracate results, than when the techniques are used alone
