MS-ECT3000 Rotary Electrochemical Corrosion Friction Wear Tester is designed for evaluating the rotating friction and wear performance of materials and films running in corrosive solutions with variation of load and rotating speed. It is mainly used for the measurement of the friction and wear measurement under corrosive solution, mainly simulating the conditions of sea, river, lake, and body fluid.

Friction properties and abrasion resistance of the material or film will be obtained through the change of the friction coefficient curve, i.e., under a specific load, after a certain time (certain distance), the friction coefficient will be changed, in that moment, the film is worn out and the wear volume will be obtained by the weighing method.

Electrochemical workstation test components include the electrochemical workstation and liquid tank. The sample is put into the sample vessel and the electrochemical changes in the friction process will be detected through the working electrode (the underneath counterpart as contact electrode) and the reference electrode.

The high-temperature friction and wear test can be conducted by heating the sample (or tank) with a set temperature.

The controlled atmosphere components extract gas through vacuum pumps and gases（N2、He and etc.） are passed in so that samples could be tested in different atmospheres.

The section area of wear scar will be obtained directly by measuring the wear depth using the detection component of the wear loss.
