Raman spectroscopy is a fast, direct, effective, accurate, and non-destructive analysis technique. In the present experiment, Raman spectroscopy is used to study the generation of a transfer layer in case of wear behaviors. Hydroxypropyl methylcellulose (HPMC) possesses the characteristics of soft films; specifically, when a load is applied to HPMC, a plowing effect is caused, thus generating a transfer layer. Via Raman spectroscopy, HPMC signals can be detected on the surface of a worn ball at a number of cycles, thus proving the generation of a transfer layer. The mechanism for the generation of a transfer layer can be observed via scanning electron microscopy and Raman spectroscopy. The results of the present research show that Raman spectroscopy can quickly ascertain the generation and consumption of a transfer layer in the contact area, and can be used for real-time monitoring of wear behaviors.
