Oxford Instruments Asylum Research Releases New Application Note: Atomic Force Microscopy Investigation of Tribofilm Formation

April 2,2020 (Santa Barbara, CA) Friction between the surfaces of mechanical systems is a costly global problem. It is not just that the resulting wear leads to premature equipment failures. Friction is also one of the leading factors that reduce energy efficiency, thought to account for more than 20% of worldwide energy consumption. Scientists and engineers in the field of tribology look for ways to reduce friction in order to reduce these economic and environmental costs. Atomic Force Microscopy (AFM) is powerful tool for investigating what happens at the nanoscale between these sliding interfaces.

The new application note examines how Asylum Research AFMs can characterize the so-called “tribofilms” that form at these interfaces. The films form over time as the material reacts with air, water, lubricants, and other compounds in the environment. These tribofilms can dramatically alter the frictional characteristics of the contact. The high-resolution imaging capabilities of Asylum AFMs allow the three-dimensional morphology of tribofilms to be imaged with nanometer-scale resolution. Examples in the paper show, however, how AFM can go far beyond simple topographic imaging. The AFM tip can be used as a tribometer, enabling reciprocating sliding wear experiments to be conducted at the nanoscale. This enables the measurement of frictional forces that vary across different regions and components of the tribofilm. Asylum Research AFMs also offer a unique set of nanomechanical characterization techniques that can measure the modulus and dissipative properties of the tribofilm. This information can help scientists and engineers understand how the tribofilms affect friction and potentially inform new strategies to reduce wear and energy losses.
