摘要：

Recently a new method to measure the adhesion and tackiness of industrial greases, based on analyzing indentation/retraction curves, has been optimized. It replaces the highly subjective finger tests that are still commonly used in the industry. This method is more versatile, it allows to use different contact geometries, material compositions and measurement parameters, whereas it provides accurate and quantitative measurements. A high precision force sensor that operates in the mN range allows to record the necessary curves. This work presents a thorough overview of this novel adhesion/tackiness measurement method. The physical meaning of indentation/retraction curves is described, as well as the importance of the contact conditions (retraction speed, applied load, grease temperature, film thickness and contact geometry). We want to highlight how to use this new method to evaluate and compare the adhesion and tackiness of various industrial greases in an efficient, unambiguous and adequate way. © 2019 Expert Verlag.
