Abrasive-sliding-electrochemical corrosion multifunctional friction wear testing machine

The invention relates to the field of friction and wear testing machines, and particularly relates to an abrasive-sliding-electrochemical corrosion multifunctional friction wear testing machine which comprises a loading mechanism, a speed regulating mechanism, a grinding head mechanism, a corrosion chamber, a rack, an electrochemical testing system, a control system and an experimental data acquisition and display system. The loading mechanism can vertically move through an electric linear guide rail; the speed regulating mechanism regulates the rotating speed through a variable frequency motor to regulate the relative movement of upper and lower samples; the grinding head mechanism is used for loading and rotating the upper sample and the lower sample by using the loading mechanism and the speed regulating mechanism; and an overflow groove is formed in the corrosion chamber so that materials and a corrosive liquid can be prevented from overflowing in an experiment process, and meanwhile, the experiment requi
