Boundary lubrication during manufacturing processes especially at spindles, gears, machining interfaces, and other areas is an aggressive tribological condition resulting in the loss of energy, materials, and overall productivity. Nano-engineered lubricants have been explored to address lubrication challenges at nano/microscopic interfaces. However, lubrication mechanism at nano/microscopic interfaces is not fully understood. This paper reports investigation on tribo-chemical lubricant film formation mechanism using techniques of four-ball tribometer, SEM/EDS, Raman spectroscopy, and TEM to understand morphology, chemistry, and structure at interfaces as lubrication progresses over time. It was found that tribo-chemical film formation showed adaptive characteristics during lubrication for progressive surface protection.
