Test Procedures
Prepare the sample by cutting or machining it to the appropriate size, and then polish and clean the sample surface.
Mount the prepared sample onto the fixture of the test platform, ensuring that the sample is securely mounted and has good contact with the counter-part.
Select a suitable electrolyte and pour it into the electrolyte tank, then install the electrode system and connect it to the electrochemical workstation.
Set the various test parameters on the control panel, including the loading force and friction speed for friction and wear testing, and the potential and current parameters for electrochemical corrosion testing.
After setting the parameters, perform a no-load test run to check if all machine components are functioning properly.
Once confirmed, officially start the test.
During the test, the operator should closely monitor the data changes on the display screen and observe the surface condition of the sample.
After the test is completed, turn off the machine power, remove the sample, observe and analyze the sample, record the test data, clean the equipment, drain the electrolyte, and perform cleaning and maintenance on the machine.
