Quantifying Tackiness and Adhesion in Greases
Standardization of test methods in the lubricants industry is neither a quick nor an easy process. “The road to standardization is quite a long road,” Emmanuel Georgiou, project and commercialization manager for Falex Tribology NV, said in a presentation at the Society of Tribologists and Lubrication Engineers Annual Meeting and Exhibition earlier this year. Georgiou and his team have been working to develop a standardized test method to quantify the tackiness and adhesion properties of grease.
A few basic steps go into standardizing such a test method. “First, you need to understand what tackiness and adhesion are,” Georgiou said. “Then you need optimize the procedure in order to have a method that relates to what you are actually observing in reality. After you have a sensitive and repeatable method, then you need to bring that to a repeatable instrument. If you manage to achieve those goals, then you are on the right track to standardize your method.”
