Bearing failure is often accompanied by hydrogen embrittlement, which was caused by hydrogen diffusion in steel. The aim of this project was to declare the effect of DLC coating on preventing hydrogen diffusion. Deuterated lubricants were used to discriminate between the original hydrogen in steel and the hydrogen generated from lubricant decomposition. After friction tests of thrust bearings, the deuterium distribution on the cross section of the raceway was analyzed using Tof-SIMS. The highest concentration of deuterium was always near the raceway surface, and the concentration decreased gradually as the depth was increased. To protect steels against the ingress of hydrogen, the effect of DLC coating, which has a low diffusion coefficient of hydrogen, was studied. DLC reduced but did not completely prevent the ingress of hydrogen, which resulted from the reduction in the amount of hydrogen generated from the tribochemical and thermal decomposition of lubricants.

In boundary lubrication, tribofilms are crucial for the management of wear and control of friction. Although a significant progress has been obtained in understanding the mechanisms of the tribofilms, the tribological properties were measured in the presence of lubricants. Strictly speaking, the measured friction forces were not the tribofilms, but the lubricants. This study focused on the tribological properties of tribofilms to make clear their antiwear and low friction mechanisms.
Using an AFM, the tribofilms’ growth were studied. Periodic changes in film thickness were observed, suggesting that the tribofilm should be generated in a dynamic process of formation and destruction. Using a self-developed friction tester, the friction coefficient distribution was firstly obtained in a larger area. The friction coefficient in micro-scale did not depend on the surface morphology, but agreed well to the chemical images of the tribofilms.
