Abstract

The invention relates to a nanoindentation/cutting test device and belongs to the field of electromechanical integration precise scientific instruments. The nanoindentation/cutting test device comprises an X/Y precise positioning platform, a Z-axis macro-motion adjusting mechanism, a precise indentation driving unit, a load signal detection unit and a displacement signal detection unit, wherein the X/Y precise positioning platform is connected with a coarse adjustment mechanism III15 through a connection plate I2, the adjustment mechanism III15 is fixed on a base 1, and a loading platform 8 is connected with the X/Y precise positioning platform through a force sensor 8; and the precise indentation driving unit is fixed on a side plate I3 through the Z-axis macro-motion adjusting mechanism, and the side plate I3 is fixed on the base 1; and the displacement signal detection unit is fixed on the base 1 through a side plate II14. The nanoindentation/cutting test device has the technical effects of compact structure and small volume. The nanoindentation/cutting test device can be used for realizing the mechanical property test of the three-dimensional test piece of which the characteristic dimension is above the millimeter level (the maximum dimension is up to 20mm*20mm*10mm); and the displacement loading resolution reaches the nanometer level and the loading force resolution reaches the micro-Newton level.

Description

technical field [0001] The invention relates to the field of opto-mechanical-electrical integration precision scientific instruments, in particular to a nano-indentation / scribing test device integrating driving, loading, detection, micro-nano mechanical performance testing and ultra-precision scribing processing. Background technique [0002] Micro-nano mechanical testing technology is a cutting-edge science and technology developed in recent years, mainly including nano-indentation (Nanoindentation), nano-scratch (Nanoscratch), atomic force microscope (AFM), micro-electromechanical system (MEMS) special testing technology ( Such as micro-stretching, etc.) and related support technologies. Among them, the nano-indentation / scratch testing technology is the most widely used, which has played an important role in the above-mentioned many fields, and promoted the researchers' in-depth research on the deformation and damage mechanism of materials. The relevant research...
