Abstract: The present invention is a nano wear testing apparatus, which preferably includes a linear motor, nano module assembly, piezoelectric member, load cell, tip mounting shaft, stage, and speaker coil. The linear motor preferably repositions the nano module assembly in close contact to the surface of a test sample, which is generally attached to the stage. The piezoelectric member moves the load cell and tip mounting shaft near the surface of the sample, and the load cell detects a contact load defined in the software application. The piezoelectric member continues to increase the load until the predetermined load for the test is reached. Once reached, the speaker coils shifts the stage at a frequency and stroke length set in the software application. During the test, the load cell and piezoelectric table continuously adjusts to keep a constant load during the test. Once the test is finished, the speaker coil stops and the load is then removed. Generally, load and depth data is recorded during the test.
