Problems solved by technology

However, when replacing probes with different functions and characterizing chemical components, the original vacuum environment will inevitably be destroyed, and many uncertain factors (such as oxygen and water vapor in the air, etc.) Real and reliable experimental data, and the above-mentioned experimental process is complex and inefficient, which seriously hinders the study of friction and wear mechanism at the micro-nano scale

Abstract

The present invention discloses an atomic force microscope-based multifunctional combined probe system. The system can switch the probes having different functions in various set working environments by the program control and in an in situ switching manner, thereby in situ realizing the functions, such as the microscopic friction and wear experiments, the surface topography scanning, the crystal structure evolution and detection, the friction energy dissipation measurement, etc., in a same experiment area. When the system switches the probes in the in situ switching manner, the working environment does not need to be destroyed, thereby avoiding the pollution of the external environment to the sample surfaces effectively.

Description
