Measurement of Surface Adhesion using Non-Contact Atomic Force Microscopy

Surface energy is a critical parameter in determining the frictional energy dissipation that occurs when two surfaces slide across each other. In this project, the influence of single atomic layers of lubricants will be placed on metallic surfaces and the impact on surface energy will be measured using non-contact atomic force microscopy. In previous studies conducted at the University of Calgary, it has been calculated that traditional methods of determining surface energy, such as through pull-off experiments and water contact angle experiments, will not provide the required accuracy and precision that is necessary to detect the change in surface energy that occurs when one atomic layer of lubricant is used, compared with two atomic layers of the lubricant. Through this collaboration, we expect to gain access to instruments that will be capable of measuring surface energy with the required precision and accuracy.
