Vacuum operated rolling contact fatigue testing machine

The test rig was used to study the performance of atomic layer deposited (ALD) coatings in mitigating RCF under inert environment such that their usefulness for space application could be determined. The computer aided design (CAD) model of the test rig along with the actual assembled test rig is illustrated in Fig. 3. The test rig is entirely LabView controlled and can be easily adapted to study the performance of different materials, coatings, and lubricants on RCF.
