of this technique in many industries. Given the limitations of traditional hardness testing techniques, nanoindentation testers are viewed as tools that can give a better understanding of the interactions between surfaces or against abrasive elements. The wealth of information about the mechanical properties derived from a nanoindentation test defines the true strength of a material. Additionally, a single tool can be used to characterize a wide variety of materials ranging from soft polymers to hard ceramics. Most importantly, this technique removes the majority of the user-influence and subjectivity from the test and allows one to quantitatively analyze a surface or coating. REFERENCES 1.
