Abstract

The invention relates to an in-situ micro-nano indentation/scratch test platform and a test method, and belongs to the field of electromechanical integrated precision scientific instruments. An X axis precision scratch unit and a Y axis large-stroke stick-slip drive scratch assembly are assembled at the tail of a base, a Z axis macro-movement adjusting mechanism is assembled at the middle of the base, a motor driving unit is assembled at the head of the base, a precision pressing driving and displacement signal detecting unit is installed on the Z axis macro-movement adjusting mechanism, and a precision three-axis force sensor used for detecting an indentation pressing force and a normal force and a tangential force of a scratch is installed on the X axis precision scratch unit. The in-situ micro-nano indentation/scratch test platform has the advantages of compact structure, miniaturization, integration, and capability of better ensuring the assembly precision, effectively improving the overall rigidity and dynamic properties and improving the overall test precision while overcoming the defect that an existing test platform cannot be used for quantitatively detecting the normal force and the tangential force in a scratch process.
