Tribological performance metrics are crucial in evaluating the effectiveness of dodecane-based lubrication systems. These metrics provide quantitative measures of how well the lubricant performs under various operating conditions, enabling engineers and researchers to optimize lubrication strategies and improve overall system efficiency.

One of the primary performance metrics is the coefficient of friction (COF). In dodecane-based systems, the COF is typically lower compared to conventional mineral oil lubricants, owing to the molecular structure of dodecane. This reduced friction translates to improved energy efficiency and reduced wear in mechanical systems.

Load-carrying capacity is a key performance indicator for lubricants, especially in heavy-duty applications. Dodecane-based systems have shown promising results in this area, with some formulations capable of withstanding loads up to 30% higher than conventional mineral oil lubricants. This enhanced load-carrying capacity is attributed to the formation of stable boundary lubrication films under extreme pressure conditions.

Viscosity index (VI) is a measure of how a lubricant's viscosity changes with temperature. Dodecane-based lubricants generally exhibit a high VI, indicating good viscosity stability across a wide temperature range. This property is particularly valuable in applications where consistent performance is required under varying thermal conditions.

Film thickness is another important metric, as it directly influences the lubricant's ability to separate moving surfaces and prevent metal-to-metal contact.
