| Abstract: | The rapid developments of surface engineering make progress in the measuring techniques for mechanical properties. This paper is specially focused on introducing measuring ways and results of Nano Indenter XP system made in MTS, such as elastic modulus, hardness , fracture toughness, film thickness, microbeam and microbridge deflection, surface roughness, critical load, friction coefficient, cross profilometry. Nano hardness techniques are the advanced ways for measuring mechanical properties of material surfaces from 103nm down to l01nm. So, it may be widely applied to quality assessment in the field of surface engineering. |
